(E)-1,2-Dichloroethene(CAS: 156-60-5)

(E)-1,2-Dichloroethene is a colorless gas with a chloroform-like odor. It has a molecular weight of approximately 98.51 g/mol and is slightly soluble in water but soluble in most organic solvents. It is relatively stable but reactive towards bases and nucleophiles. It has a boiling point of 39.8°C and a melting point of -50°C.

(E)-1,2-Dichloroethene can be synthesized by the chlorination of acetylene in the presence of a Lewis acid catalyst such as aluminum chloride. The reaction is conducted under anhydrous conditions and at elevated temperatures. The yield is around 80-90%, and the reaction is selective towards the (E)-isomer.

(E)-1,2-Dichloroethene is primarily used in the production of vinyl chloride, which is a key monomer for the synthesis of polyvinyl chloride (PVC). It is also used in the production of various chlorinated compounds and as a solvent in some industrial processes.

When handling (E)-1,2-Dichloroethene, appropriate personal protective equipment (PPE) such as gloves, goggles, and a respirator should be worn. It should be handled in a well-ventilated area or a fume hood. Spills should be contained and cleaned up using absorbent materials. Proper storage should be in a cool, dry place, away from sources of ignition. Always consult the Safety Data Sheet (SDS) for detailed safety information.
