The reactions of 1,1,1-trichloroethane and 1,1-dichloroethene vapours with solid aluminium(III) chloride have been studied using Fourier-transform i.r. spectroscopy to determine stoicheiometries as a function of time.Dehydrochlorination of 1,1,1-trichloroethane to give 1,1-dichloroethene and hydrogen chloride appears to be the only important process in the initial stage of the reaction, but the 1,1-dichloroethene formed reacts with the solid phase and the main product is a mixture of involatile chlorohydrocarbon species.The quantity of hydrogen chloride evolved indicates that the involatile material is highly unsaturated and in both reactions AlCl3 becomes progressively coated with a strongly purple-coloured tar.Small quantities of carbon tetrachloride are also produced in both reactions.
