Ethylene, ethyl chloride, and 1,2-dichloroethane are obtained as major byproducts. Vinyl chloride monomer (VCM) is the key chemical precursor to PVC. [2], Vinyl chloride can also be obtained as a byproduct in the synthesis of chlorofluorocarbons when saturated chlorofluorocarbons are catalytically dechlorinated by ethylene. et al. Web-based case management solution that helps nonprofits estimate service needs by geographical area. Terms of Use - May 22–29, 1970. Y    [31], In the late 1960s, the cancers that all of these studies warned of finally manifested themselves in workers. Smaller amounts of vinyl chloride are used in furniture and automobile upholstery, wall coverings, housewares, and automotive parts. U    [30] In 1972, Maltoni, another Italian researcher for the European vinyl chloride industry, found liver tumors (including angiosarcoma) from vinyl chloride exposures as low as 250 ppm for four hours a day. Hence, to save the processing cost for manufacturing ethylene, numerous attempts have been made to convert ethane directly to vinyl chloride. Maltoni, C. "Cancer Detection and Prevention" (1972) Presented at the Second International Symposium on Cancer Detection and Prevention. Vinyl chloride is a mutagen having clastogenic effects which affect lymphocyte chromosomal structure. Vinyl chloride has also been used in the past as a refrigerant.
