1,2-Dichloroethene, commonly called 1,2-dichloroethylene or 1,2-DCE, is an organochloride with the molecular formula C2H2Cl2. It is a highly flammable, colorless liquid with a sharp, harsh odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two. They have modest solubility in water. These compounds have few industrial applications, although they are fundamental given their simple stoichiometries.

1,2-Dichloroethene What is the equation for the reaction of 12dichloroethene with

Production

cis-DCE, the Z isomer, is obtainable by the controlled chlorination of acetylene:

C2H2 + Cl2 → C2H2Cl2 1,2-Dichloroethene C2h

Industrially both isomers arise as byproduct of the production of vinyl chloride, which is produced on a vast scale. Unlike vinyl chloride, the 1,2-dichloroethylene isomers do not polymerize.

trans-DCE has applications including electronics cleaning, precision cleaning, and certain metal cleaning applications.

Safety

These compounds have "moderate oral toxicity to rats."
