2-Chloro-1-propanol Chemical Properties,Usage,Production

Chemical Properties

Propylene chlorohydrin is a colorless liquid.

Chemical Properties

Colorless liquid; mild, nonresidual odor. Soluble in water and alcohol.

Uses

In preparation of propylene oxide, q.v.

Uses

Propylene β-chlorohydrin is used in the pro duction of propylene oxide.

Uses

2-Chloropropanol is used as a solvent in the composition and method for removing a coating from a surface. 2-Chloropropanol is used as an organic solvent in liquid cleaner for the removal of post-etch residues from microsprocessors.

Synthesis Reference(s)

Journal of the American Chemical Society, 72, p. 4353, 1950 DOI: 10.1021/ja01166a005

General Description

Clear colorless liquid with a pleasant odor.

Air & Water Reactions

Water soluble.

Reactivity Profile

2-Chloro-1-propanol may be sensitive to prolonged exposure to light. 2-Chloro-1-propanol can react with oxidizing agents. .

Hazard

Moderate fire risk. Toxic by ingestion and skin absorption. Liver damage. Questionable car- cinogen.

Health Hazard

Propylene β-chlorohydrin is a moderatelytoxic compound having irritant actions onthe skin and eyes. Instilling 2.2 mg of liquidcaused severe eye irritation in rabbits. It cancause poisoning via ingestion, inhalation, andskin absorption. Exposure to 500 ppm for4 hours was lethal to rats. The lethal dosein dogs by oral intake was 200 mg/kg. Thetarget organs are the CNS, gastrointestinalsystem, liver, and kidney.
LD50 value, skin (rabbits): 529 mg/kg
Studies conducted to determine increasedrisks of pancreatic and lymphopoietic can cer among workers in ethylene and propylene chlorohydrin production remained inconclu sive and have given inconsistent findings(Olsen et al. 1997).

Fire Hazard

2-Chloro-1-propanol is flammable.

Safety Profile

Poison by ingestion. Moderately toxic by inhalation and skin contact. A skin and severe eye irritant. Flammable liquid when exposed to heat, flame, or powerful oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of Cl-.

Potential Exposure

This material is used in organic synthesis; to make other chemicals.

Shipping

UN2611Propylene chlorohydrin, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid.

Incompatibilities

Vapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Alcohols are sensitive to light and oxi- dation. It is unstable in solution. It undergoes hydrolysis in aqueous buffers. Contact with alkali metals, nitrides, and strong reducing agents may form flammable and/or toxic gases. May react with anhydrides forming acids and esters, generating noticeable heat, and also with oxoacids and carboxylic acids to form esters plus water, but the heat of reaction in the latter case typically is low. May initiate the polymerization of isocyanates and epoxides.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
