Method for preparation of polyvinyl chloride resin (PVC) monomer
Industry of polyvinyl chloride (PVC) the methods to prepare monomer mainly acetylene method, combination method, ethylene oxychlorination, ethylene balanced oxychlorination.
1, acetylene method. Acetylene and hydrogen chloride is the first method to realize the industrialization of acetylene by calcium carbide (Tan Huagai) and the role of water. This method has great power consumption, and it is currently used in the production of vinyl chloride PVC resin factory mainly concentrated in our country, accounting for 70% of the total amount of PVC resin.
2, combined method. Ethylene was produced by the process of oil cracking, which was produced with two chlorine ethane, and then heated and cracked under the pressure.
3, ethylene oxychlorination. The use of ethylene, hydrogen chloride and oxygen reaction to get two chlorine ethane and water, two chlorine ethane and then cracked, the formation of vinyl chloride. By-product hydrogen chloride recycling to process oxygen chloride, reaction to.
4, balanced oxychlorination of ethylene. Is the direct chlorination and oxygen chlorination process. Ethylene reacts with chlorine to produce two chlorine ethane, which is produced by the cracking of the two chlorine ethane. Hydrogen chloride reacts with ethylene and oxygen to produce two of the chlorine, and two of the chlorine ethane to produce chlorine and hydrogen chloride. After the recovery of hydrogen chloride, continue to participate in the reaction of oxygen and chlorine.
