Chemische Eigenschaften
Colorless to pale-yellow liquid; characteristic odor. Soluble in water, alcohols, and ethers; insoluble in hydrocarbons. Combustible.
Verwenden
3-Chloro-1-propanol is used in organicsynthesis to produce cyclopropane andtrimethylene oxide. It is an intermediate inthe synthesis of pharmaceuticals, agrochemicals, antiseptic agents, and dyes. It is an inhibitor of triosephosphate isomerase and glyceraldehyde 3-phosphate dehydrogenase.
synthetische
3-Chloro-1-propanol is synthesized by the reaction of 1, 3-propanediol and hydrochloric acid, using benzene sulfonic acid as the catalyst.
Reaction: 250 g of trimethylene glycol are shaken with 450 g of sulfur chloride, the mixture becoming warm, sulfur dioxide being rapidly evolved, and sulfur deposited. This reaction continues for 1 hours without heating, whereafter the mixture is heated for a further 6 hours on the water-bath and then for 30 min, over a free flame. When no more sulfur dioxide is evolved, the mixture is allowed to cool, then extracted several times with ether. The sulfur is washed with ether, and the united ethereal layers are shaken with sodium carbonate solution to remove sulfur dioxide, dried over sodium sulfate, and freed from ether. The residue is fractionated and the fraction of b.p. 140-180° C is redistilled, giving 60% (160 g) of 3-chloro-1-propanol, b.p. 160-164°C/760 mm, 60-64° C/10 mm.

Allgemeine Beschreibung
3-Chloro-1-propanol appears as a colorless liquid with a mild odor. Slightly denser than water. Toxic by ingestion and inhalation . Flash point 270°F. Used to make plastics, resins and other chemicals.
Reaktivität anzeigen
3-Chloro-1-propanol may be sensitive to prolonged exposure to light. 3-Chloro-1-propanol may react with oxidizing agents. .
Health Hazard
3-Chloro-1-propanol also know as Trimethylene chlorohydrin, is a moderatelytoxic compound. Skin contact can cause irritation.Ingestion can result in CNSdepression, muscle contraction, gastrointesti nal pain, and ulceration or stomach bleed ing. High dosage can cause liver injury. Thetoxicity of this compound, however, is lesssevere than that of its isomer, propylene β-chlorohydrin.
LD50 value, oral (mice): 2300 mg/kg
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.
Sicherheitsprofil
Moderately toxic by ingestion. Mutation data reported. Chloropropanols have mutagenic and carcinogenic properties. The 3-monochloropropanol (3-MCPD) is the main chloropropanol found in hydrolyzates of vegetable protein (HVP) made by acid hydrolysis.
Waste disposal
Trimethylene chlorohydrin is burned in achemical incinerator equipped with an afterburner and scrubber.
