The major side-product is the related compound 1,1,2-trichloroethane, from which the 1,1,1-trichloroethane can be separated by distillation. A somewhat smaller amount of 1,1,1-trichloroethane is produced from the reaction of 1,1-dichloroethene and hydrogen chloride in the presence of an iron(III) chloride catalyst: CH 2 =CCl 2 + HCl → CH 3 CCl 3
The demand for TCE as a degreaser began to decline in the 1950s in favor of the less toxic 1,1,1-trichloroethane. However, 1,1,1-trichloroethane production has been phased out in most of the world under the terms of the Montreal Protocol due to its contribution to the ozone depletion. As a result, trichloroethylene has experienced some ...
Trichloroethane (C 2 H 3 Cl 3) may refer to either of two isomeric chemical compounds: 1,1,1-Trichloroethane (methyl chloroform, CCl 3 CH 3) 1,1,2-Trichloroethane ...
Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class (alkanes with one or more hydrogens substituted by chlorine) includes common examples. The wide structural variety and divergent chemical ...
A trihalide in chemistry is an organohalide consisting of three halide atoms bonded to a single atom or compound. [1] [2] An example of a trihalide is chloroform. The trihalomethanes are the simplest trihalides, because only one hydrogen is connected to the carbon. The 1,1,1-Trichloroethane is one of the trihalides of ethane.
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2 FC−CClF 2 . This colorless, volatile liquid is a versatile solvent.
[3] [4] Historically 1,1,1-Trichloroethane was used, sometimes together with Tetrachloroethylene. It was phased out because of its ozone-depleting nature. [5] Non-chlorinated brake cleaners use hydrocarbons as a main component; it will either be a low-boiling aliphatic compound or higher-boiling hydrocarbon mixture.
It is mainly used as a feedstock in chemical synthesis, chiefly of 1,1,1-trichloroethane. It is also used as a solvent for plastics , oils and fats , as a degreaser , as a fumigant in insecticide sprays, in halon fire extinguishers , and in cementing of rubber .
