登记用途：Uses: Most of the vinyl chloride produced is used to make polyvinyl chloride (PVC)、a material widely used in automotive parts、packaging products、pipes、construction materials、furniture、and a variety of other products.、The highest exposures to vinyl chloride occurred in polyvinyl chloride polymerization plants during reactor vessel cleaning. [LaDou、p. 520]、See 29 CFR 1910.1017、Smoking cigarettes [Category: Food & Drugs]、About 99% of the global vinyl chloride capacity is used for the production of poly(vinyl chloride) (PVC) and its copolymers.、In the plastics industry to manufacture polyvinyl chloride、in organic syntheses. Has been used as refrigerant、spray can propellant.、Monomer for、polyvinyl chloride and copolymers、organic synthesis、adhesives for plastics.、Used in a wide variety of copolymers ... Starting material for the synthesis of a variety of industrial compounds ... The primary nonpolymeric uses of vinyl chloride are in the manufacture of vinylidene chloride、vinyl stearate and tri- and tetrachloroethylene.、For more Uses (Complete) data for Vinyl chloride (14 total)、please visit the HSDB record page.、Vinyl chloride is used primarily to make polyvinyl chloride (PVC). PVC is used in a variety of plastic products、such as pipes、wire and cable coatings、and packaging materials. Small amounts of vinyl chloride is sometimes used in furniture and automobile upholstery、wall coverings、housewares、and automotive parts. (L3)、Use Classification: Chemical Classes -> Volatile organic compounds、Food Contaminant -> CONTAMINANT -> JECFA Functional Classes、Industry Uses: Monomers、Intermediate、Consumer Uses: Monomers、Methods of Manufacturing: (1) Dehydrochlorination of ethylene dichloride、(2) reaction of acetylene and hydrogen chloride、either as liquids or gases.、Prepared from ethylene dichloride and alcoholic potassium、... by halogenation of ethylene.、The catalytic hydrochlorination of acetylene is possible in either the gaseous or the liquid phase. The gas-phase reaction dominates in industrial processes. In this process the gaseous reactants are brought into contact with the catalyst at slightly increased pressure (0.1-0.3 MPa) and 100-250 °C (contact time 0.1-1 seconds) and then are quenched and partially liquefied. The reaction products are separated、recycled、or submitted to final purification.、In the crack gas processes for vinyl chloride manufacture、unpurified acetylene produced by high-temperature cracking of naphtha or methane is used. These processes are advantageous in that they do not require the cost-intensive separation of acetylene-ethylene mixtures. The crack gas is fed directly to the hydrochlorinator、and the acetylene is converted to vinyl chloride、which is then separated from the remaining constituents. Because all of the acetylene is consumed、the remaining ethylene is more easily separated、or it can be introduced to a direct chlorination stage、where it is chlorinated to 1、2-dichloroethane、which is subsequently cracked to vinyl chloride. Because almost equimolar amounts of ethylene and acetylene can be achieved in the crack gas、the process can be balanced for chlorine.、Impurities: Commercial grade contains 1-2% impurities: water、non-volatile residues、acetaldehyde、hydrogen chloride、hydrogen peroxide、and methyl chloride.、Specifications for a typical commercial product call for maxima in mg、kg by weight of the following impurities: unsaturated hydrocarbons - 10、acetaldehyde - 2、dichloro compounds - 16、water - 15、hydrogen chloride - 2、nonvolatiles - 200、iron - 0.4. Phenol at levels of 25-50 mg、kg by weight is used as a stabilizer to prevent polymerization.、The impurities、of vinyl chloride are as follows:、acetic aldehyde 5 ppm、butane 8 ppm、1、3-butadiene 10 ppm、chlorophene 10 ppm、diacetylene 4 ppm、vinyl acetylene 10 ppm、propine 3 ppm、methylchloride 100 ppm.、Formulations、Preparations: Grade: Technical、pure 99.9%、Vinyl chloride monomer is available commercially in cylinders or in bulk and is generally supplied as a liquid under pressure.、Liquefied gas、polymer grade、Consumption Patterns: MONOMER FOR POLY(VINYL CHLORIDE) RESINS、85%、EXPORTS、13.5%、MISCELLANEOUS (MOSTLY COPOLYMER USE)、1.5% (1982)、95% FOR POLYVINYL CHLORIDE HOMOPOLYMER AND COPOLYMER RESIN、4% FOR SYNTHESIS OF METHYL CHLOROFORM、1% FOR MISC APPLICATIONS (1972)、91% FOR POLYVINYL CHLORIDE、CHEMICAL PROFILE: Vinyl Chloride. Polyvinyl chloride、91%、exports、7%、other、including chlorinated solvents、2%.、For more Consumption Patterns (Complete) data for Vinyl chloride (7 total)、U.S. Production: 2023: 15、000、000 - <20、000 lb、2022: 15、2021: 15、2020: 15、(1977) 2.72X10+12 G、(1982) 2.22X10+12 G、(1985) 4.30X10+12 G、(1986) 8.41X10+9 lb、For more U.S. Production (Complete) data for Vinyl chloride (15 total)、U.S. Imports: (1977) 6.05X10+5 G、(1982) 2.30X10+10 G、(1985) 5.89X10+10 G、(1986) 2.06X10+8 lb、U.S. Exports: (1978) 4.08X10+11 G、(1983) 3.11X10+11 G、(1985) 4.61X10+11 G、(1987) 8.43X10+8 lb、(1996) 2.2 billion pounds、General Manufacturing Information: Plastics Material and Resin Manufacturing、All Other Chemical Product and Preparation Manufacturing、Petrochemical Manufacturing、Ethene、chloro-: ACTIVE、Because it has been confirmed that vinyl chloride monomer is a human and animal carcinogen、sale of propellants and all aerosols containing it was banned in 1974.、The most important vinyl monomer.、Dichloroethane used for pyrolysis to vinyl chloride must be of purity greater than 99.5 wt % because cracking process is highly susceptible to inhibition. It must also be dry to prevent excessive corrosion.。
