1,1,2-Trichloroethane is an organic compound from the group of organochlorine compounds and aliphatic chlorinated hydrocarbons. It is isomeric to 1,1,1-trichloroethane .

Extraction and presentation

1,1,2-trichloroethane can be produced by further chlorination of 1,2-dichloroethane .

properties

1,1,2-trichloroethane is a sweet-smelling liquid that is poorly soluble in water. Their vapors are much heavier (4.61 times as heavy) than air.

1,1,2-trichloroethane decomposes on intense heating or in bright light, producing various chlorine compounds (e.g. hydrogen chloride , phosgene ).

use

1,1,2-Trichloroethane is mainly used as an intermediate in the production of other organochlorine compounds such as vinylidene chloride (by splitting off HCl). As a solvent , it has only limited use for dissolving chlorinated rubber .

safety instructions

1,1,2-trichloroethane is very toxic to the heart, liver and kidneys. The use of 1,1,2-trichloroethane in products outside of chemical plants or in products from which a release is possible is prohibited.
