It is a colorless liquid with a sweet chloroform-like odor. It is used as a solvent and in the production of wood stains and varnishes. It is an isomer of 1,1,2,2-tetrachloroethane. It was likely discovered by Auguste Laurent along with the 1,1,2,2-tetrachloroethane isomer and trichloroethylene in 1836.Essai sur l'Action du Chlore sur la Liqueur des Hollandais et sur quelques Ethers in Annales de Chimie, LXIII.

R. Brown in American Journal of Pharmacy, vol. 37, page 289 Production 1,1,1,2-Tetrachloroethane can be obtained by a two-step addition reaction of acetylene with chlorine (via dichloroethylene), but this mainly produces 1,1,2,2-tetrachloroethane. C2H2 + Cl2 -> C2H2Cl2 C2H2Cl2 + Cl2 -> C2H2Cl4 It can be obtained directly by chlorination of 1,1,2-trichloroethane:Lawrance Waddams: The Petroleum chemicals Industry, S. 175.
