75-01-4 - Preparation Method
Open Data Verified Data
- ethylene oxychlorination is recognized as a technically and economically reasonable method in the world. Ethylene and chlorine in the presence of ferric chloride catalyst, liquid phase direct chlorination of 1,2 dichloroethane. 1,2-= ethylene chloride is refined and cracked to obtain vinyl chloride and hydrogen chloride, and the finished vinyl chloride is obtained by rectification. Hydrogen chloride, ethylene and air are by-produced, and 1,2-= ethyl chloride is obtained by oxychlorination through a copper chloride catalyst supported on alumina, and then refined at 500 ° C. And 2.O ~ 2. 5MPa pressure, in the tube furnace cracking of vinyl chloride and hydrogen chloride, refined products of vinyl chloride. The by-product hydrogen chloride may then be returned to the oxychlorination reactor for further oxychlorination with ethylene.
- acetylene gas phase synthesis method this method has the advantages of simple process, high product purity, but large power consumption, high cost, and mercury pollution problems. The acetylene generated by calcium carbide is mixed with hydrogen chloride, and the reaction is carried out at 170~190 ℃ in the presence of mercury chloride. The reaction product is washed with water, alkali washing, compression, full coagulation, primary distillation and rectification, vinyl chloride monomer.
- ethylene direct chlorination process
- combined alkyne method

75-01-4 - Safety
Open Data Verified Data
- has anesthetic effect on human body. Content of 20% ~ 40%, can make the people of acute poisoning and loss of consciousness, breathing gradually slow, eventually leading to death. Long-term contact can cause phalanx dissolubility or hepatosplenomegaly and other symptoms. It has also been reported that vinyl chloride can cause cancer, but there is some controversy. When acute poisoning is found, it should be removed from the scene as soon as possible, lying still and keeping warm, loose coat, oxygen or artificial respiration. If the skin is contaminated with liquid, it should be washed with plenty of water. Production equipment should be strictly prevented from running, dripping, dripping and leakage. The operator should wear protective gear. The maximum allowable concentration in air is 1 × 10-6.
- can be stored and transported in pipes and pressure storage tanks. Should be isolated from the flame, avoid and oxidant close to prevent sun, heat, transport to prevent impact. It can be transported by road and railway.
