Properties：Trans -1, 2- dichloroethylene is a colorless to yellowish transparent liquid. Smells like chloroform. Flammable, its steam and air can form explosive mixture. It will explode if exposed to open fire and high heat. It can react strongly with the oxidant. It is possible to form explosive chloroacetylene with copper and its alloys. Heated in the air, it will decompose and release the highly toxic phosgene and hydrogen chloride gases. Soluble in alcohol, ether and other organic solvents, insoluble in water. Boiling point(101.3kPa): 47.7ºC; Melting point: -49.4ºC; Relative density(20/4ºC): 1.2565g/mL; Refractive index(N20ºC): 1.4457; Flash point(opening): 6ºC.
Uses：Trans-1, 2-dichloroethylene can be used as paint, resin, wax, rubber, acetate fiber and other polymer materials of organic solvents, so it often used for preparation of varnish and rubber solution; It can also be used as a metal and electronic detergent, as well as used in dry cleaning agent, insecticide, fungicide, anesthetic, low temperature extraction agent and refrigerant. With the deepening of research, trans-1, 2-dichloroethylene is more and more widely used, the latest research shows that trans-1, 2-dichloroethylene can also be used to produce high-end polyurethane foaming agent. It has no damage to the atmosphere. Therefore, with the increasing awareness of environmental protection, developing trans-1, 2-dichloroethylene products has obvious economic and social benefits.
Storage：Keep sealed and store in a cool and ventilated warehouse. Keep away from fire and heat sources. Stored separately from Oxidants and acids.
Packing：250kg steel barrel
