应用领域

登记用途：Uses: Ethylene dichloride is primarily used in the production of vinyl chloride as well as other chemicals. It is used in solvents in closed systems for various extraction and cleaning purposes in organic synthesis. It is also added to leaded gasoline as a lead scavenger. It was formerly used in ore flotation、as a grain fumigant、as a metal degreaser、and in textile and PVC cleaning.、Used in organic synthesis、used in the past as a solvent、degreaser、paint remover、and fumigant、[ACGIH] Has been used as a dry cleaning agent and solvent for degreasing、resins、adhesives、cosmetics、and pharmaceuticals、[HSDB]、Use as fumigant suspended by EPA due to toxicity. [Sullivan、p. 1053]、Metal Degreasing [Category: Clean]、Working with Glues and Adhesives [Category: Other]、Plastic Composites Manufacturing [Category: Industry]、For 1、2-dichloroethane (USEPA、OPP Pesticide Code: 042003) there are 0 labels match.、SRP: Not registered for current use in the U.S.、but approved pesticide uses may change periodically and so federal、state and local authorities must be consulted for currently approved uses.、The majority of the total EDC production is used for the production of vinyl chloride. Some EDC is used in the production of chlorinated solvents、such as 1、1、1-trichloroethane and tri- and tetrachloroethylene. The rest goes into various processes mainly for the synthesis of ethylenediamines. Its use as a solvent (dewaxing、deparaffinizing petroleum fractions、and coating remover) is marginal.、Manufacture of vinyl chloride、acetyl cellulose、solvent for fats、oils、waxes、gums、and particularly for rubber. Has been used as an insect and soil fumigant. Organic solvent.、Fumigant、Former use、For more Uses (Complete) data for 1、2-Dichloroethane (9 total)、please visit the HSDB record page.、The most common use of 1、2-dichloroethane is in the production of vinyl chloride which is used to make a variety of plastic and vinyl products including polyvinyl chloride (PVC) pipes、furniture and automobile upholstery、wall coverings、housewares、and automobile parts. It is also used as a solvent and is added to leaded gasoline to remove lead. Exposure occurs mainly by breathing air or drinking water contaminated with 1、2-dichloroethane. Humans can be exposed to low levels of 1、2-dichloroethane through the skin or air by contact with old products made with 1、2-dichloroethane. (L156)、Use Classification: Chemical Classes -> Volatile organic compounds、Food Additives -> EXTRACTION_SOLVENT -> JECFA Functional Classes、FUMIGANTS、Industry Uses: Monomers、Solvent、Intermediate、Soil amendments (fertilizers)、Flame retardant、Consumer Uses: Intermediate、Methods of Manufacturing: 1、2-Dichloroethane is produced by the vapor- or liquid-phase chlorination of ethylene. Most liquid-phase processes use small amounts of ferric chloride as the catalyst. Other catalysts claimed in the patent literature include aluminum chloride、antimony pentachloride、and cupric chloride and an ammonium、alkali、or alkaline-earth tetrachloroferrate. The chlorination is carried out at 40-50 °C with 5% air or other free-radical inhibitors added to prevent substitution chlorination of the product. Selectivities under these conditions are nearly stoichiometric to the desired product. The exothermic heat of reaction vaporizes the 1、2-dichloroethane product、which is purified by distillation.、Oxychlorination of ethylene has become the second important process for 1、2- dichloroethane. The process is usually incorporated into an integrated vinyl chloride plant in which hydrogen chloride、recovered from the dehydrochlorination or cracking of 1、2-dichloroethane to vinyl chloride、is recycled to an oxychlorination unit. The hydrogen chloride by-product is used as the chlorine source in the chlorination of ethylene in the presence of oxygen and copper chloride catalyst.、Action of chlorine on ethylene、with subsequent distillation with metallic catalyst、also by reaction of acetylene and hydrochloric acid.、Made from ethylene and chlorine、also from acetylene and HCl ... .、For more Methods of Manufacturing (Complete) data for 1、2-Dichloroethane (6 total)、Formulations、Preparations: Grades: Technical、spectrophotometric.、2-Dichloroethane、commercial formulation、70% active ingredient.、Consumption Patterns: Demand: 13.9x10+9 lb (1991)、14.3X10+9 lb (1992)、16.5X10+9 lb (1996) (forecast)、includes exports of 1.45x10+9 lb (1991) but not imports estimated at 11X10+6 lb、Vinyl chloride monomer、88%、exports、10%、other including chlorinated solvents and ethyleneamines、2%.、... 85% of total ...production used for production of vinyl chloride、10% used in the production of chlorinated solvents...
