| Applications | Uses: Used as a solvent and chemical intermediate, [ACGIH] Used as a refrigerant, degreaser, dry cleaning agent, and solvent for perfumes, adhesives, lacquers, oils, and resins, [HSDB] Only the trans isomer is commercially available in the US--used for precision cleaning of electronic components and a small amount used as a blowing agent for specialty foams, [EPA Toxicological Review, 2010], Metal Degreasing [Category: Clean], Semiconductor Manufacturing [Category: Industry], Painting (Solvents) [Category: Paint], Working with Glues and Adhesives [Category: Other], Dry Cleaning [Category: Clean], Plastic Composites Manufacturing [Category: Industry], Used as a solvent for fats, phenol, camphor, etc. and as an intermediated for chlorinated solvents and compounds, [Merck Index] Also used to make rubber, as a refrigerant, an additive (dyes, lacquer solutions, medicines, perfumes, and thermoplastics), and to retard fermentation, [NTP] The trans- isomer is used industrially more than the cis- isomer or the commercial mixture, [HSDB], ... Used as a solvent for waxes, resins and acetylcellulose. It is also used in the extraction of rubber, in the manufacture of pharmaceuticals and artificial pearls, and in the extraction of oils and fats from fish and meat., 1, 2-Dichloroethylene, Current uses for trans-1, 2-DCE include its use as a degreasing agent and as one component of formulated products used for precision cleaning of electronic components. A small amount is used as a blowing agent for specialty foam., Cis- and trans-isomers of 1, 2-dichloroethylene have had only limited use as solvents and chemical intermediates. Neither of the isomers has developed wide industrial usage in the USA partly because of their flammability., 2-Dichloroethylenes can be used as solvent for waxes, resins, and thermoplastics, for the extraction of oil and fats from fish and meat, for vapor degreasing, as surface cleaning agent, for the extraction of rubber, as foam blowing additive, as refrigerant, in the manufacture of pharmaceuticals, and as source of HCl in silicone etching., 2-Dichloroethylenes, Due to its more favorable environmental and toxicological properties trans-1, 2-dichloroethylene is marketed as an alternative to methylene chloride, trichloroethylene, and n-propyl bromide in solvent applications. Its flammability is a disadvantage and hence nonflammable mixtures of trans-1, 2-dichloroethylene and hydrofluorocarbons have been developed., Trans-1, 2-DCE is used as a solvent for waxes, acetylcellulose, dyes, thermoplastics, fats, and phenols. It is also used as an intermediate in the preparation of other chlorinated solvents. One may be exposed by breathing contaminated air, eating, or drinking the substance, or by skin contact (L585, L586)., Use Classification: Chemical Classes -> Volatile organic compounds, Industry Uses: Solvent, Semiconductor and photovoltaic agent, Not Known or Reasonably Ascertainable, Cleaning agent, Propellants, non-motive (blowing agents), Intermediate, Consumer Uses: Semiconductor and photovoltaic agent, Solvent, Household Products: Information on 3 consumer products that contain Trans-1, 2-Dichloroethylene in the following categories is provided:, • Commercial, Institutional, • Inside the Home, Methods of Manufacturing: Preparation of trans-form: Adler, United States of America patent 2440997 (1948 to Stockholms Superfosfot Fabriks Aktiebolag)., Dichloroethylenes (cis: [156-59-2], trans: [156-60-5]) often occur as an isomeric mixture during the production of chlorinated hydrocarbons, where they are produced by sidereactions, e.g., by thermal decomposition of 1, 2-trichloroethane or from acetylene by chlorine addition. The isomers can be separated by fractional distillation., In the thermal dehydrochlorination of 1, 2-trichloroethane, the 1, 2-dichloroethylenes are obtained together with the 1, 1-isomer. With increasing temperature, formation of the 1, 2-isomers increases. The trans isomer is preferentially formed. With catalysts, the individual ratios can be varied to some extent., Consumption Patterns: In applications where dichloroethylenes could be used as solvents and for low temperature extraction processes, they have been replaced by methylene chloride., Dichloroethylenes, U.S. Production: 2023: 1, 000, 000 - <5, 000 lb, 2022: 1, 2021: 1, 2020: 1, trans-1, 2-Dichloroethylene is listed as a High Production Volume (HPV) chemical (65FR81686).
