- Beschreibung Acetone is a flammable, colorless liquid with a pleasant odor. It is used widely as an organic solvent and in the chemical industry. It is the simplest ketone, which also goes by the name dimethyl ketone (DMK). Acetone was originally referred to as pyroacetic spirit because it was obtained from the destructive distillation of acetates and acetic acid.
- Chemische Eigenschaften A clear liquid with characteristic aromatic odor; pungent, somewhat sweet taste. It is used as a flavor enhancer, flavoring agent or adjuvant solvent, or vehicle washing or surface removal agent. Its quick miscibility with water, alcohol, ether, chloroform and most volatile oils makes acetone a valuable solvent and extractant
- Chemische Eigenschaften Acetone, CH3COCH3, also known as 2-propanone and dimethylketone, is a colorless, volatile,flammable liquid that boils at 56°C (133 OF). It is misciblewith water and is oftenused as a solventin the manufacture of lacquers and paints.
- Chemische Eigenschaften Acetone is a highly flammable, colorless liquid with a sweet, mint-like odor
- Chemische Eigenschaften Acetone is a colorless volatile, flammable, transparent liquid, with a sweetish odor and pungent sweetish taste.
- Physikalische Eigenschaften Clear, colorless, liquid with a sweet, fragrant odor. Sweetish taste. Odor threshold concentrations ranged from 42 ppmv (Nagata and Takeuchi, 1990) to 100 ppmv (Leonardos et al., 1969). Experimentally determined detection and recognition odor threshold concentrations were 48 mg/m3 (20 ppmv) and 78 mg/m3 (33 ppmv), respectively (Hellman and Small, 1974).
- Occurrence Reported found in apple, pear, grape, pineapple, strawberry, raspberry, tomato, black currant, citrus, onion and potato; also reported found in cocoa leaves, in Mexican goosefoot and in the oils of coriander and lavender. In trace amounts it has been reportedly identified in the oil of bitter orange, in distilled wine and in coffee aroma
The traditional method of producing acetone in the 19th century and the beginning of the 20th century was to distill acetates, particularly calcium acetate, Ca(C2H3O2)2.
Weizmann discovered a process to produce butyl alcohol and acetone from the bacterium Clostridium acetobutylicum in 1914. With England’s urgent demand for acetone, Winston Churchill (1874–1965) enlisted Weizmann to develop the Weizmann process for acetone production on an industrial scale. Fermentation and distillation techniques for acetone production were replaced starting in the 1950s with the cumene oxidation process . In this process, cumene is oxidized to cumene hydroperoxide, which is then decomposed using acid to acetone and phenol. This is the primary method used to produce phenol, and acetone is produced as a co-product in the process, with a yield of about 0.6:1 of acetone to phenol.
- Verwenden Acetone is used in the manufacture of a largenumber of compounds, such as acetic acid,chloroform, mesityl oxide, and MIBK; in themanufacture of rayon, photographic films,and explosives; as a common solvent; inpaint and varnish removers; and for purifyingparaffins.
Acetone is used in the chemical industry in numerous applications. The primary use of acetone is to produce acetone cyanohydrin, which is then used in the production of methyl methacrylate (MMA). Another use of acetone in the chemical industry is for bisphenol A (BPA). BPA results form the condensation reaction of acetone and phenol in the presence of an appropriate catalyst. BPA is used in polycarbonate plastics, polyurethanes, and epoxy resins. Polycarbonate plastics are tough and durable and are often used as a glass substitute.
In addition to its use as a chemical feedstock and intermediate, acetone is used extensively as an organic solvent in lacquers, varnishes, pharmaceuticals, and cosmetics. Nail polish remover is one of the most common products containing acetone. Acetone is used to stabilize acetylene for transport .
- Verwenden Acetone′s luminesence intensity is dependent upon the solution components 1. The absorption of UV light by acetone, results in its photolysis and the production of radials 1.
- Verwenden Suitable for HPLC, spectrophotometry, environmental testing
- Verwenden Used in liquid chromotography; cleaning glassware; extraction of solid waste.
- Verwenden Solvent for fats, oils, waxes, resins, rubber, plastics, lacquers, varnishes, rubber cements. manufacture of methyl isobutyl ketone, mesityl oxide, acetic acid (ketene process), diacetone alcohol, chloroform, iodoform, bromoform, explosives, aeroplane dopes, rayon, photographic films, isoprene; storing acetylene gas (takes up about 24 times its vol of the gas); extraction of various principles from animal and plant substances; in paint and varnish removers; purifying paraffin; hardening and dehydrating tissues. Pharmaceutic aid (solvent).
- Verwenden acetone is a solvent considered to be non-comedogenic and occasionally used in skin toners. It is primarily used in nail polish remover. It could be drying and very irritating to the skin depending on the concentration and frequency of use.
- Definition ChEBI: A methyl ketone that consists of propane bearing an oxo group at C2.
- Vorbereitung Methode Acetone can also be produced from isopropanol using several methods, but the main methodis by catalytic dehydrogenation.
- Vorbereitung Methode Acetone is obtained by fermentation as a by-product of n-butyl alcohol manufacture, or by chemical synthesis from isopropyl alcohol; from cumene as a by-product in phenol manufacture; or from propane as a by-product of oxidation-cracking.
- Aroma threshold values Detection: 40 to 476 ppm
- Allgemeine Beschreibung A clear colorless liquid with a sweetish odor. Flash point 0°F. Less dense than water. Vapors are heavier than air. Used as a solvent in paint and nail polish removers.
- Air & Water Reaktionen Highly flammable. Water soluble.
- Reaktivität anzeigen Acetone was reported that a mixture of Acetone and chloroform, in a residue bottle, exploded. Since addition of Acetone to chloroform in the presence of base will result in a highly exothermic reaction, Acetone is thought that a base was in the bottle [MCA Case History 1661. 1970]. Also, Nitrosyl chloride, sealed in a tube with a residue of Acetone in the presence of platinum catalyst, gave an explosive reaction [Chem. Eng. News 35(43):60. 1967]. The reaction of nitrosyl perchlorate and Acetone ignites and explodes. Explosions occur with mixtures of nitrosyl perchlorate and primary amine [Ann. Chem. 42:2031. 1909]. Reacts violently with nitric acid. Also causes exothermic reaction when in contact with aldehydes.
- Health Hazard INHALATION: vapor irritating to eyes and mucous membranes; acts as an anesthetic in very high concentrations. INGESTION: low order of toxicity but very irritating to mucous membranes. SKIN: prolonged excessive contact causes defatting of the skin, possibly leading to dermatitis.
- Health Hazard The acute toxicity of acetone is low. Acetone is primarily a central nervous system depressant at high concentrations (greater than 12,000 ppm). Unacclimated volunteers exposed to 500 ppm acetone experienced eye and nasal irritation, but it has been reported that 1000 ppm for an 8-hour day produced no effects other than slight transient irritation to eyes, nose, and throat. Therefore there are good warning properties for those unaccustomed to working with acetone; however, frequent use of acetone seems to cause accommodation to its slight irritating properties. Acetone is practically nontoxic by ingestion. A case of a man swallowing 200 mL of acetone resulted in his becoming stuporous after 1 hour and then comatose; he regained consciousness 12 hour later. Acetone is slightly irritating to the skin, and prolonged contact may cause dermatitis. Liquid acetone produces moderate transient eye irritation. Acetone has not been found to be carcinogenic in animal tests or to have effects on reproduction or fertility.
The acute toxicity of acetone in testanimals was found to be low. However,in large dosages it could be moderatelytoxic. Inhalation can cause irritation ofthe eyes, nose, and throat. A shortexposure for 5 minutes to 300–500 ppmcan be slightly irritating to humans. Theodor threshold is 200–400 ppm. In highconcentrations it can produce dryness in themouth, fatigue, headache, nausea, dizziness,muscle weakness, loss of coordinatedspeech, and drowsiness. Ingestion cancause headache, dizziness, and dermatitis.Swallowing 200–250 mL can result invomiting, stupor, and coma in humans. Adose of 25 mg/kg may be fatal to dogs.
LD50 value, oral (rats): 5800 mg/k No mutagenic or carcinogenic effects havebeen reported.
- Brandgefahr Acetone is extremely flammable (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and "flash back." Acetone vapor forms explosive mixtures with air at concentrations of 2 to 13% (by volume). Carbon dioxide or dry chemical extinguishers should be used for acetone fires.
- Brandgefahr HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
- Flammability and Explosibility Acetone is extremely flammable (NFPA rating = 3), and its vapor can travel a considerable distance to an ignition source and "flash back." Acetone vapor forms explosive mixtures with air at concentrations of 2 to 13% (by volume). Carbon dioxide or dry chemical extinguishers should be used for acetone fires.
- Pharmazeutische Anwendungen Acetone is used as a solvent or cosolvent in topical preparations, and as an aid in wet granulation.It has also been used when formulating tablets with water-sensitive active ingredients, or to solvate poorly water-soluble binders in a wet granulation process. Acetone has also been used in the formulation of microspheres to enhance drug release.Owing to its low boiling point, acetone has been used to extract thermolabile substances from crude drugs.
- Industrielle Verwendung Acetone is valuable solvent component in acrylic/nitrocellulose automotive lacquers. Acetone is the solvent of choice in film coatings operations which use vinylidene chloride-acrylonitrile copolymer formulations.Other ketones that may be used in these film coating operations include methyl isobutyl ketone, ethyl n-amyl ketone, and diisobutyl ketone.Acetone, blends of MIBK and MEK, methyl namyl ketone, ethyl n-amyl ketone, and diisobutyl ketone are all useful solvents for vinyl resin copolymers. The presence of one of the slower evaporating ketones in the solvent blend prevents quick drying, improves flow, and gives blush resistance to the coating. Acetone is also used as a resin thinner in polyester resins and as a clean up solvent for the resin reactor kettle.In solvents industry, Acetone is a component of solvent blends in urethane, nitrile rubber, and neoprene industrial adhesives.Acetone is the primary solvent in resin-type adhesives and pressure sensitive chlorinated rubber adhesives. Acetone also can be used to extract fats, oils, waxes, and resins from natural products, to dewax lubricating oils, and to extract certain essential oils.Acetone is also an important chemical intermediate in the preparation of several oxygenated solvents including the ketones, diacetone alcohol, mesityl oxide, methyl isobutyl ketone, and isophorone.

Naturally occurs in blood and urine in small concentrations. Reported in cigarette smoke
(1,100 ppm) and gasoline exhaust (2.3 to 14.0 ppm) (quoted, Verschueren, 1983).
Acetone occurs naturally in many plant species including cuneate Turkish savory (Satureja cuneifolia), catmint (Nepeta racemosa), Guveyoto (Origanum sipyleum), and Topukcayi shoots (Micromeria myrtifolia) at concentrations of 20, 2, 2, and 0.1, respectively (Baser et al., 1992, 1993; Ozek et al., 1992; Tumen, 1991). Acetone was also detected in Turkish calamint (Calamintha nepeta ssp. glandulosa) (Kirimer et al., 1992), pineapples, cauliflower leaves, tea leaves, West Indian lemongrass, jimsonweed, soybeans, carrots, bay leaves, hop flowers, apples, tomatoes, water mint leaves, alfalfa, pears, rice plants, white mulberries, clover-pepper, and roses (Duke, 1992). Acetone also was emitted from many forest plant species (Isidorov et al., 1985).
Acetone was detected in diesel fuel at a concentration of 22,000 μg/g (Schauer et al., 1999). Identified as an oxidative degradation product in the headspace of a used engine oil (10–30W) after 4,080 miles (Levermore et al., 2001). Acetone also was detected in automobile exhaust at concentrations ranging from 0.09 to 4.50 mg/m3 (Grimaldi et al., 1996) and in cigarette smoke at concentrations ranging from 498 to 869 mg/m3 (Euler et al., 1996).
Gas-phase tailpipe emission rates from California Phase II reformulated gasoline-powered automobiles with and without catalytic converters were 1.19 and 42 mg/km, respectively (Schauer et al., 2002).
Vereecken and Peeters (2000) reported that acetone is formed from the reaction of α-pinene and OH radicals in the atmosphere. This reaction resulted in an acetone yield of 8.5% which is consistent with available experimental data.
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rates of acetone were 749 mg/kg of pine burned, 462 mg/kg of oak burned, and 79 mg/kg of eucalyptus burned.
Biological. Following a lag time of 20 to 25 h, acetone degraded in activated sludge (30 mg/L)
at a rate constant ranging from 0.016 to 0.020/h (Urano and Kato, 1986). Soil bacteria can mineralize acetone to carbon dioxide (Taylor et al., 1980). Bridié et al. (1979) reported BOD and
COD values of 1.85 and 1.92 g/g using filtered effluent from a biological sanitary waste treatment
plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d.
Similarly, Heukelekian and Rand (1955) reported a 5-d BOD value of 0.85 g/g which is 38.5% of
the ThOD value of 2.52 g/g. Waggy et al. (1994) reported 5, 15, and 28-d BOD values of 14, 74,
and 74%, respectively. Using the BOD technique to measure biodegradation, the mean 5-d BOD
value (mM BOD/mM acetone) and ThOD were 1.52 and 38.0%, respectively (Vaishnav et al.,
Photolytic. Photolysis of acetone in air yields carbon monoxide and free radicals, but in isopropanol, pinacol is formed (Calvert and Pitts, 1966). Photolysis of acetone vapor with nitrogen dioxide via a mercury lamp gave peroxyacetyl nitrate as the major product with smaller quantities of methyl nitrate (Warneck and Zerbach, 1992).
Chemical/Physical. Hypochlorite ions, formed by the chlorination of water for disinfection purposes, may react with acetone to form chloroform. This reaction is expected to be significant within the pH range of 6 to 7 (Stevens et al., 1976).
- Lager Acetone should be stored in a cool, dry, well-ventilated place out of direct sunlight.
- Lager Acetone should be used only in areas free of ignition sources, and quantities greater than 1 liter should be stored in tightly sealed metal containers in areas separate from oxidizers.

- läuterung methode The commercial preparation of acetone by catalytic dehydrogenation of isopropyl alcohol gives relatively pure material. Analytical reagent quality generally contains less than 1% of organic impurities but may have up to about 1% of H2O. Dry acetone is appreciably hygroscopic. The main organic impurity in acetone is mesityl oxide, formed by aldol condensation. It can be dried with anhydrous CaSO4, K2CO3 or type 4A Linde molecular sieves, and then distilled. Silica gel and alumina, or mildly acidic or basic desiccants cause acetone to undergo the aldol condensation, so that its water content is increased by passage through these reagents. This also occurs to some extent when P2O5 or sodium amalgam is used. Anhydrous MgSO4 is an inefficient drying agent, and CaCl2 forms an addition compound. Drierite (anhydrous CaSO4) offers minimum acid and base catalysis for aldol formation and is the recommended drying agent for this solvent [Coetzee & Siao Inorg Chem 14 2 1987, Riddick & Bunger Organic Solvents Wiley-Interscience, N.Y., 3rd edn, 1970]. Acetone can be shaken with Drierite (25g/L) for several hours before it is decanted and distilled from fresh Drierite (10g/L) through an efficient column, maintaining atmospheric contact through a Drierite drying tube. The equilibrium water content is about 10-2M. Anhydrous Mg(ClO4)2 should not be used as drying agent because of the risk of EXPLOSION with acetone vapour. Organic impurities have been removed from acetone by adding 4g of AgNO3 in 30mL of water to 1L of acetone, followed by 10mL of M NaOH, shaking for 10minutes, filtering, drying with anhydrous CaSO4 and distilling [Werner Analyst (London) 58 335 1933]. Alternatively, successive small portions of KMnO4 have been added to acetone at reflux, until the violet colour persists, followed by drying and distilling. Refluxing with chromium trioxide (CrO3) has also been used. Methanol has been removed from acetone by azeotropic distillation (at 35o) with methyl bromide, and treatment with acetyl chloride. Small amounts of acetone can be purified as the NaI addition compound, by dissolving 100g of finely powdered NaI in 400g of boiling acetone, then cooling in ice and salt to -8o. Crystals of NaI.3Me2CO are filtered off and, on warming in a flask, acetone distils off readily. [This method is more convenient than the one using the bisulfite addition compound.] It has also been purified by gas chromatography on a 20% free fatty acid phthalate (on Chromosorb P) column at 100o. For efficiency of desiccants in drying acetone see Burfield and Smithers [J Org Chem 43 3966 1978]. The water content of acetone can be determined by a modified Karl Fischer titration [Koupparis & Malmstadt Anal Chem 54 1914 1982]. [Beilstein 1 IV 3180.] Rapid procedure: Dry over anhydrous CaSO4 and distil.
- Inkompatibilitäten May explode when mixed with chloroform, chromic anhydride. Incompatible with acids, bases, and oxidizing materials, such as peroxides, chlorates, perchlorates, nitrates, and permanganates. Unstable peroxides formed with strong oxidizers. May accumulate static electrical charges and may cause ignition of its vapors. Dissolves most rubber, resins, and plastics.
- Inkompatibilitäten Acetone reacts violently with oxidizing agents, chlorinated solvents, and alkali mixtures. It reacts vigorously with sulfur dichloride, potassium t-butoxide, and hexachloromelamine. Acetone should not be used as a solvent for iodine, as it forms a volatile compound that is extremely irritating to the eyes.
