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 ...
1,1,1-Trichloroethane is an excellent solvent for many organic compounds and also one of the least toxic of the chlorinated hydrocarbons.It is generally considered non-polar, but owing to the good polarizability of the chlorine atoms, it is a superior solvent for organic compounds that do not dissolve well in hydrocarbons such as hexane.
1,1,2-Trichloroethane, vinyl trichloride or 1,1,2-TCA, is an organochloride solvent with the molecular formula C 2 H 3 Cl 3 and the structural formula CH 2 Cl—CHCl 2. It is a colourless , sweet-smelling liquid that does not dissolve in water , but is soluble in most organic solvents .

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 .
Others from this series were Perklone (Tetrachloroethylene), Triklone (Trichloroethylene), Methoklone (Dichloromethane) and Genklene (1,1,1-Trichloroethane). [15] [16] CFC-113 is one of the three most popular CFCs, along with CFC-11 and CFC-12. [17] CFC-113 in laboratory analytics has been replaced by other solvents. [18]
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 (vinyl trichloride, CHCl 2 CH 2 Cl)
2,2,2-Trichloroethanol is the chemical compound with formula Cl 3 C−CH 2 OH.Its molecule can be described as that of ethanol, with the three hydrogen atoms at position 2 (the methyl group) replaced by chlorine atoms.
