Description

cis-1,2-Dichloroethylene (cis-DCE, cis-1,2-C2H2Cl2, CAS registry No. 156-59-2) is a colorless liquid. Its melting point is −80 oC. It is soluble in alcohol, ether, and most other organic solvents. The reaction of cis-DCE and potassium hydroxide can produce chloroacetylene, which is explosive and spontaneously flammable in air. It is highly toxic. So, it is incompatible with moist air or water, bases. When heated to decomposition, it yields hydrogen chloride, carbon monoxide, carbon dioxide. cle
