While the chemical is not used in consumer products manufactured in the U.S., a case was reported in 2009 of molded plastic consumer products (toys and holiday decorations) from China that released 1,2-dichloroethane into homes at levels high enough to produce cancer risk. [13] [14] Substitutes are recommended and will vary according to ...

1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2. The two compounds are isomers, each being colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes, chemical and ...
Side products include carbon tetrachloride, hydrogen chloride, and hexachlorobutadiene. Several other methods have been developed. When 1,2-dichloroethane is heated to 400 °C with chlorine , tetrachloroethylene is produced:
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness.The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak.

On an industrial scale, base-promoted dehydrohalogenations as described above are disfavored. The disposal of the alkali halide salt is problematic. Instead thermally-induced dehydrohalogenations are preferred. One example is provided by the production of vinyl chloride by heating 1,2-dichloroethane: [3] CH 2 Cl-CH 2 Cl → CH 2 =CHCl + HCl
It is also produced by direct chlorination or oxychlorination utilizing ethylene as feedstock and by catalytic chlorination of ethane or chlorination of 1,2- dichloroethane. [8] 1,1,2,2-Tetrachloroethane is always produced in closed systems to obtain the highest yield. Common side products that are created during the synthesis of 1,1,2,2 ...
