Category

Chlorinated Aliphatics

Description

Colorless liquid with a pleasant odor; [CAMEO] Clear light yellow liquid; [Sigma-Aldrich MSDS]

Sources/Uses

Used as a solvent for fats, phenol, camphor, etc. and as an intermediated for chlorinated solvents and compounds; [Merck Index] Also used to make rubber, as a refrigerant, an additive (dyes, lacquer solutions, medicines, perfumes, and thermoplastics), and to retard fermentation; [NTP] The trans- isomer is used industrially more than the cis- isomer or the commercial mixture; [HSDB]

Comments

Forms unstable peroxides in air that may spontaneously explode; [CAMEO] A skin, eye, mucous membrane, and upper respiratory tract irritant; May cause CNS intoxication and transient renal effects; [NTP] Exposure to concentrations of 2,200 ppm causes burning of eyes, vertigo, and nausea; Twice as toxic as the cis- isomer; [HSDB] Human inhalation of 4,800 mg/m3 for 10 minutes causes sleep and hallucinations; [RTECS] A skin and strong eye irritant; Prolonged or repeated exposure may cause narcosis; Harmful by ingestion; Targets the CNS, liver, and kidney; [Sigma-Aldrich MSDS] See "1,2-Dichloroethylene, all isomers."
