- Beschreibung Acetic acid is a colourless liquid or crystal with a sour, vinegar-like odour and is one of the simplest carboxylic acids and is an extensively used chemical reagent. Acetic acid has wide application as a laboratory reagent, in the production of cellulose acetate mainly for photographic film and polyvinyl acetate for wood glue, synthetic fibres, and fabric materials. Acetic acid has also been of large use as a descaling agent and acidity regulator in food industries.
- Chemische Eigenschaften Description: Acetic acid is a colorless liquid or crystals with a sour, vinegar-like odor. Pure compound is a solid below 17 C. Often used in an aqueous solution. Glacial acetic acid contains 99% acid.
- Chemische Eigenschaften Clear colorless liquid
- Chemische Eigenschaften Glacial acetic acid occurs as a crystalline mass or a clear, colorless volatile solution with a pungent odor.
Acetic acid, CH3COOH, is a colorless, volatile liquid at ambient temperatures. The pure compound, glacial acetic acid,
owes its name to its ice-like crystalline appearance at 15.6°C. As generally supplied, acetic acid is a 6 N aqueous solution (about 36%)
or a 1 N solution (about 6%). These or other dilutions are used in adding appropriate amounts of acetic acid to foods. Acetic acid is
the characteristic acid of vinegar, its concentration ranging from 3.5 to 5.6%. Acetic acid and acetates are present in most plants and
animal tissues in small but detectable amounts. They are normal metabolic intermediates, are produced by such bacterial species as
Acetobacter and can be synthesized completely from carbon dioxide by such microorganisms as Clostridium thermoaceticum. The
rat forms acetate at the rate of 1% of its body weight per day.
As a colorless liquid with a strong, pungent, characteristic vinegar odor, it is useful in butter, cheese, grape and fruit flavors. Very little pure acetic acid as such is used in foods, although it is classified by FDA as a GRAS material. Consequently, it may be employed in products that are not covered by Definitions and Standards of Identity. Acetic acid is the principal component of vinegars and pyroligneous acid. In the form of vinegar, more than 27 million lb were added to food in 1986, with approximately equal amounts used as acidulants and flavoring agents. In fact, acetic acid (as vinegar) was one of the earliest flavoring agents. Vinegars are used extensively in preparing salad dressing and mayonnaise, sour and sweet pickles and numerous sauces and catsups. They are also used in the curing of meat and in the canning of certain vegetables. In the manufacture of mayonnaise, the addition of a portion of acetic acid (vinegar) to the salt- or sugar-yolk reduces the heat resistance of Salmonella. Water binding compositions of sausages often include acetic acid or its sodium salt, while calcium acetate is used to preserve the texture of sliced, canned vegetables
- Physikalische Eigenschaften Acetic acid is a weak carboxylic acid with a pungent odor that exists as a liquid at room temperature. It was probably the first acid to be produced in large quantities. The name acetic comes from acetum, which is the Latin word for “sour” and relates to the fact that acetic acid is responsible for the bitter taste of fermented juices.
- Occurrence Reported found in vinegar, bergamot, cornmint oil, bitter orange oil, lemon petitgrain, various dairy products
- History Vinegar is a dilute aqueous solution of acetic acid. The use of vinegar is well documented in ancient history, dating back at least 10,000 years. Egyptians used vinegar as an antibiotic and made apple vinegar. Babylonians produced vinegar from wine for use in medicines and as a preservative as early as 5000 b.c.e. Hippocrates (ca. 460–377 b.c.e.), known as the “father of medicine,” used vinegar as an antiseptic and in remedies for numerous conditions including fever, constipation, ulcers, and pleurisy. Oxymel, which was an ancient remedy for coughs, was made by mixing honey and vinegar. A story recorded by the Roman writer Pliny the Elder (ca. 23–79 c.e.) describes how Cleopatra, in an attempt to stage the most expensive meal ever, dissolved pearls from an earring in vinegar wine and drank the solution to win a wager.
Acetic acid is an important industrial chemical. The reaction of acetic acid with hydroxyl containing compounds, especially alcohols, results in the formation of acetate esters. The largest use of acetic acid is in the production of vinyl acetate . Vinyl acetate can be produced through the reaction of acetylene and acetic acid. It is also produced from ethylene and acetic acid. Vinyl acetate is polymerized into polyvinyl acetate (PVA), which is used in the production of fibers, films, adhesives, and latex paints.
Cellulose acetate, which is used in textiles and photographic film, is produced by reacting cellulose with acetic acid and acetic anhydride in the presence of sulfuric acid. Other esters of acetic acid, such as ethyl acetate and propyl acetate, are used in a variety of applications.
Acetic acid is used to produce the plastic polyethylene terephthalate (PET) . Acetic acid is used to produce pharmaceuticals.

- Verwenden Glacial Acetic Acid is an acidulant that is a clear, colorless liquid which has an acid taste when diluted with water. It is 99.5% or higher in purity and crystallizes at 17°c. It is used in salad dressings in a diluted form to provide the required acetic acid. It is used as a preservative, acidulant, and flavoring agent. It is also termed acetic acid, glacial.
- Verwenden It is used in aqueous and non-aqueous acid-base titrations.
- Verwenden manufacture of various acetates, acetyl compounds, cellulose acetate, acetate rayon, plastics and rubber in tanning; as laundry sour; printing calico and dyeing silk; as acidulant and preservative in foods; solvent for gums, resins, volatile oils and many other substances. Widely used in commercial organic syntheses. Pharmaceutic aid (acidifier).
- Definition ChEBI: A simple monocarboxylic acid containing two carbons.
Alchemists used distillation to concentrate acetic acid to high purities. Pure acetic acid isoften called glacial acetic acid because it freezes slightly below room temperature at 16.7°C(62°F). When bottles of pure acetic acid froze in cold laboratories, snowlike crystals formedon the bottles; thus the term glacial became associated with pure acetic acid. Acetic acidand vinegar were prepared naturally until the 19th century. In 1845, the German ChemistHermann Kolbe (1818–1884) successfully synthesized acetic acid from carbon disulfide (CS2). Kolbe’s work helped to establish the field of organic synthesis and dispelled the idea of vitalism. Vitalism was the principle that a vital force associated with life was responsible for all organic substances.
Acetic acid is used in numerous industrial chemical preparations and the large-scale productionof acetic acid takes place through several processes. The main method of preparation ismethanol carbonylation. In this process, methanol reacts with carbon monoxide to give aceticacid: CH3OH(l) + CO(g) → CH3COOH(aq). Because the reaction requires high pressures (200atmospheres), this method was not used until the 1960s, when the development of specialcatalysts allowed the reaction to proceed at lower pressures. A methanol carbonylation proceduredeveloped by Monsanto bears the company’s name. The second most common methodto synthesize acetic acid is by the catalytic oxidation of acetaldehyde: 2 CH3CHO(l) + O2(g) →2 CH3COOH(aq). Butane may also be oxidized to acetic acid according to the reaction: 2 C4H10(l) +5O2(g) → 4 CH3COOH(aq) + 2H2O(l). This reaction was a major source of acetic acid beforethe Monsanto process. It is carried out at a temperature of approximately 150°C and 50 atmospheres pressure.
- Vorbereitung Methode Acetic acid is usually made by one of three routes: acetaldehyde oxidation, involving direct air or oxygen oxidation of liquid acetaldehyde in the presence of manganese acetate, cobalt acetate, or copper acetate; liquid-phase oxidation of butane or naphtha; methanol carbonylation using a variety of techniques.
- Definition A dilute solution (about 4% by volume) of ETHANOIC ACID (acetic acid), often with added coloring and flavoring such as caramel. Natural vinegar is produced by the bacterial fermentation of cider or wine; it can also be made synthetically.
- Definition vinegar: A dilute solution ofethanoic acid (up to 6%), used as aflavouring and pickling medium. Naturalvinegar is made by the continuedfermentation of alcoholicliquors, usually by Acetobacter species,which oxidize ethanol to ethanoicacid. Vinegar is also made by dilutingsynthetic ethanoic acid.

- Hazard Corrosive; exposure of small amounts can severely erode the lining of the gastrointestinal tract; may cause vomiting, diarrhea, bloody feces and urine; cardiovascular failure and death.
- Health Hazard Corrosive to the skin and eyes; vapor or mist is very irritating and can be destructive to the eyes, mucous membranes, and respiratory system; ingestion causes internal irritation and severe injury.
- Health Hazard TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Glacial acetic acid is a highly corrosive liquid. Contact with the eyes can produce mild to moderate irritation in humans. Contact with the skin may produce burns. Ingestion of this acid may cause corrosion of the mouth and gastrointestinal tract. The acute toxic effects are vomiting, diarrhea, ulceration, or bleeding from intestines and circulatory collapse. Death may occur from a high dose (20–30 mL), and toxic effects in humans may be felt from ingestion of 0.1–0.2 mL. An oral LD50 value in rats is 3530 mg/kg (Smyth 1956).
Glacial acetic acid is toxic to humans andanimals by inhalation and skin contact. Inhumans, exposure to 1000 ppm for a fewminutes may cause eye and respiratory tractirritation. Rabbits died from 4-hour exposureto a concentration of 16,000 ppm in air.
- Brandgefahr Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
- Brandgefahr Acetic acid is a combustible substance (NFPA rating = 2). Heating can release vapors that can be ignited. Vapors or gases may travel considerable distances to ignition source and "flash back." Acetic acid vapor forms explosive mixtures with air at concentrations of 4 to 16% (by volume). Carbon dioxide or dry chemical extinguishers should be used for acetic acid fires.
- Flammability and Explosibility Acetic acid is a combustible substance (NFPA rating = 2). Heating can release vapors that can be ignited. Vapors or gases may travel considerable distances to ignition source and "flash back." Acetic acid vapor forms explosive mixtures with air at concentrations of 4 to 16% (by volume). Carbon dioxide or dry chemical extinguishers should be used for acetic acid fires.
- Pharmazeutische Anwendungen Glacial and diluted acetic acid solutions are widely used as acidifying agents in a variety of pharmaceutical formulations and food preparations. Acetic acid is used in pharmaceutical products as a buffer system when combined with an acetate salt such as sodium acetate. Acetic acid is also claimed to have some antibacterial and antifungal properties.

Acetic acid is widely used in pharmaceutical applications primarily
to adjust the pH of formulations and is thus generally regarded as
relatively nontoxic and nonirritant. However, glacial acetic acid or
solutions containing over 50% w/w acetic acid in water or organic
solvents are considered corrosive and can cause damage to skin,
eyes, nose, and mouth. If swallowed glacial acetic acid causes severe
gastric irritation similar to that caused by hydrochloric acid.
Dilute acetic acid solutions containing up to 10% w/w of acetic acid have been used topically following jellyfish stings.Dilute acetic acid solutions containing up to 5% w/w of acetic acid have also been applied topically to treat wounds and burns infected with Pseudomonas aeruginosa.
The lowest lethal oral dose of glacial acetic acid in humans is reported to be 1470 mg/kg.The lowest lethal concentration on inhalation in humans is reported to be 816 ppm.Humans, are, however, estimated to consume approximately 1 g/day of acetic acid from the diet.
LD50 (mouse, IV): 0.525 g/kg
LD50 (rabbit, skin): 1.06 g/kg
LD50 (rat, oral): 3.31 g/kg
From the destructive distillation of wood from acetylene and water and from acetaldehyde by subsequent oxidation with
air. Pure acetic acid is produced commercially by a number of different processes. As dilute solutions, it is obtained from alcohol by
the “Quick-Vinegar Process.” Smaller quantities are obtained from the pyroligneous acid liquors acquired in the destructive distillation of hard wood. It is manufactured synthetically in high yields by the oxidation of acetaldehyde and of butane, and as the reaction
product of methanol and carbon monoxide
Vinegars are produced from cider, grapes (or wine), sucrose, glucose or malt by successive alcoholic and acetous fermentations. In the United States, the use of the term “vinegar,” without qualifying adjectives, implies only cider vinegar. Although a 4 to 8% solution of pure acetic acid would have the same taste characteristics as cider vinegar, it could not qualify as a vinegar, since it would lack other readily detectable components characteristic of cider vinegar. In Great Britain, malt vinegar is specified. On the European continent, wine vinegar is the most common variety
- mögliche Exposition Acetic acid is widely used as a chemical feedstock for the production of vinyl plastics, acetic anhydride, acetone, acetanilide, acetyl chloride, ethyl alcohol, ketene, methyl ethyl ketone, acetate esters, and cellulose acetates. It is also used alone in the dye, rubber, pharmaceutical, food preserving, textile, and laundry industries. It is utilized, too; in the manufacture of Paris green, white lead, tint rinse, photographic chemicals, stain removers, insecticides, and plastics.
- Enzyminhibitor This two-carbon alkyl acid (FW = 60.05 g/mol; CAS 64-19-7) is the most common carboxylic acid in biological systems. Acetate is the anion form or conjugate base of acetic acid, which has a pKa value of 4.76 at 25°C (the dpKa/dT value is +0.0002). The acid is a colorless liquid (M.P. = 16.7°C; B.P. = 118°C) with a distinctively strong and pungent odor. Acetic acid is miscible with water, ethanol, diethyl ether, glycerol, and carbon tetrachloride. The pure acid is often referred to as glacial acetic acid because, when poured on a surface, it resembles ice in appearance. Note that, just as water has an autoprotolysis constant of 10–14 M2 at 24°C, the autoprotolysis constant for glacial acetic acid is 10–13 M2 at 25°C. Salts of acetic acid (e.g., sodium acetate, ammonium acetate, etc.) are very hygroscopic and are very soluble in water; for example, 119 g of sodium acetate dissolve in 100 mL water at 0°C and 253 g potassium acetate dissolve in 100 mL water at 20°C.

- läuterung methode Usual impurities are traces of acetaldehyde and other oxidisable substances and water. (Glacial acetic acid is very hygroscopic. The presence of 0.1% water lowers its m by 0.2o.) Purify it by adding some acetic anhydride to react with water present, heat it for 1hour to just below boiling in the presence of 2g CrO3 per 100mL and then fractionally distil it [Orton & Bradfield J Chem Soc 960 1924, Orton & Bradfield J Chem Soc 983 1927]. Instead of CrO3, use 2-5% (w/w) of KMnO4, and boil under reflux for 2-6hours. Traces of water have been removed by refluxing with tetraacetyl diborate (prepared by warming 1 part of boric acid with 5 parts (w/w) of acetic anhydride at 60o, cooling, and filtering off, followed by distillation [Eichelberger & La Mer J Am Chem Soc 55 3633 1933]. Refluxing with acetic anhydride in the presence of 0.2g % of 2-naphthalenesulfonic acid as catalyst has also been used [Orton & Bradfield J Chem Soc 983 1927]. Other suitable drying agents include anhydrous CuSO4 and chromium triacetate: P2O5 converts some acetic acid to the anhydride. Azeotropic removal of water by distillation with thiophene-free *benzene or with butyl acetate has been used [Birdwhistell & Griswold J Am Chem Soc 77 873 1955]. An alternative purification uses fractional freezing. [Beilstein 2 H 96, 2 IV 94.] Rapid procedure: Add 5% acetic anhydride, and 2% of CrO3. Reflux and fractionally distil.
