Vinyl chloride, also known as Vinyl chloride, is an important monomer used in polymer chemical industry and can be made from ethylene or acetylene. It is a colorless, easily liquefied gas with a boiling point of -13 ° C, a critical temperature of 151.5 ° C, and a critical pressure of 5.57 MPa. The relative density is 2.2%. Vinyl chloride is a toxic substance, and long-term inhalation and exposure to vinyl chloride may cause liver cancer. It forms an explosive mixture with air, with an explosion limit of 3.6% to 33% by volume. It is more explosive under pressure. Attention should be paid to the sealing and nitrogen sealing of the container during storage and transportation, and a small amount of polymerization inhibitor should be added.
On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a preliminary list of carcinogens, and vinyl chloride was listed on a list of carcinogens.
The main raw materials of vinyl chloride: Thiopropionic Acid, 3-Mercaptopropionic acid, Thiopropionic acid, 3-Thiopropanoic acid, beta-Mercaptopropionic acid.
1. Mainly used to make homopolymers and copolymers of polyvinyl chloride. It can also be copolymerized with vinyl acetate, butadiene, etc., and can also be used as an extractant for dyes and perfumes. It is used as a comonomer for a variety of polymers, an important raw material for the plastics industry, and can also be used as a refrigerant.
2. An important raw material for the plastics industry, mainly used in the production of polyvinyl chloride resins. Copolymerized with vinyl acetate, vinylidene chloride, butadiene, acrylonitrile, acrylates and other monomers to form copolymers, and can also be used as a refrigerant.
3. Mainly used in the manufacture of polyvinyl chloride. It can also be copolymerized with vinyl acetate, butadiene, acrylonitrile, acrylate, vinylidene chloride, etc. to make adhesives, coatings, food packaging materials, building materials, and the like. It can also be used as an extractant for dyes and perfumes.
4. Used as a raw material for plastics and for organic synthesis, also as a refrigerant.
