| 应用领域 | Uses: Used as an intermediate、dye carrier、transformer fluid、solvent、coolant、and heat transfer medium、Used in lubricants and insecticides、[HSDB]、Chem intermediate eg、for 2、3-dichlorophenol、constituent of trichlorobenzene mixt used for termite control、SRP: Former use、and as transformer fluid、dye carrier & solvent、Solvent for high melting products、Coolant in electrical installations and glass tempering、Polyester dyeing、Lubricants、Heat transfer medium、insecticides.、Organic intermediate、Trichlorobenzene ... has been used as a soil treatment to repel or poison termites around the foundation of buildings. The technical product is a mixture of the 1、2、3- and 1、4- isomers.、Former use、Trichlorobenzene is used as a solvent in chemical manufacturing、as well as in dyes、dielectric fluid、synthetic transformer oils、lubricants、heat-transfer medium、and insecticides. (T39)、Methods of Manufacturing: ... Production method applicable to 1、4- and 1、3-trichlorobenzenes is based on the dehydrohalogenation of 1、3、4、5、6-hexachlorocyclohexane (stereoisomeric mixture)、a byproduct of gamma-hexachlorocyclohexane production. In the presence of aqueous alkali or alkaline earth solutions or of ammonia、or directly through use of catalysts、hexachlorocyclohexane is converted at a temperature of 90 - 250 °C mainly to trichlorobenzene. The yield lies between 80 and 99%、with the product mixture consisting of 70 - 85% 1、4-trichlorobenzene and 13 - 30% 1、3-trichlorobenzene.、The batch reaction of benzene with a 2.8-fold molar quantity of chlorine in the presence of ferric chloride at temperatures increasing to 100 °C gives a chlorination mixture consisting of 26% 1、4-dichlorobenzene、4.5% 1、2-dichlorobenzene、48% 1、4-trichlorobenzene、8% 1、3-trichlorobenzene、4-tetrachlorobenzene、5.5% 1、5-tetrachlorobenzene、and less than 1% pentachlorobenzene. The proportion of 1、and thus also of 1、can be raised by adding sulfur compounds as cocatalysts. After the chlorination mixture has been neutralized it can be separated by fractional distillation provided a column with more than 60 practical plates is used.、Chlorination of o-dichlorobenzene in the presence of ferric chloride、followed by distillation.、Formulations、Preparations: AI3-15516、U.S. Production: (1982) 51、300 to 163、000 lb、Benzene、1、3-trichloro- is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B、51FR21438).、Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#3183]、Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#3184]、U.S. Imports: (1979) 1.4X10+9 G-PRINCIPAL CUSTOMS DISTRIBUTORS、(1983) 1.39X10+9 g、3- AND 1、4-TRICHLOROBENZENE、General Manufacturing Information: Benzene、3-trichloro-: ACTIVE、3-Trichlorobenzene is formed in minor amounts during the production of monochlorobenzene. |
