What is 1,2-Dichloroethane

1,2-Dichloroethane is clear colorless liquid with a chloroform-like odor. The chemical compound 1,2-dichloroethane, commonly known by its old name of ethylene dichloride (EDC), is a chlorinated hydrocarbon, the major precursor for PVC production. It is insoluble in water.It is highly flammalbe. Its melting point is-35 °C  and the  boiling point is 83 °C(lit.).
1,2-Dichloroethane can be used as solvents in the pharmaceutical industry and process intermediates in the chemical industry.This product should be stored from 0°C to 6°C. It is mainly used to produce vinyl chloride monomer (VCM, chloroethene. Dioxolane and toluene are possible substitutes as solvents. Dichloroethane is unstable in the presence of aluminium metal and, when moist, with zinc and iron.
As a good apolar aprotic solvent, 1,2-dichloroethane is used as degreaser and paint remover. As a useful 'building block' reagent, it is used as an intermediate in the production of various organic compounds such as ethylenediamine. In the laboratory it is occasionally used as a source of chlorine, with elimination of ethene and chloride.
