Abstract

Reactions of hydrogen with chloroform and 1, 1, 2-trichloroethane were studied in a tubular reactor at a pressure of 1 atm and in the temperatures range of 550-1100 °C. Reagent loss and product formation were monitored by using an on-line gas chromatograph, where batch samples were analyzed by GC/mass spectrometry. The major products of reactions of hydrogen with chloroform and 1, 1, 2-trichloroethane above 850 °C were observed as the thermodynamically stable species HCl, CH4, and carbon (solid). The more stable chlorinated byproducts, chloromethane and vinyl chloride, were also observed at low concentrations, and higher temperatures were required for the subsequent decomposition of these products. Complete destruction of the parent reagent, chloroform and 1, 1, 2-trichloroethane, was observed at temperatures near 700 °C with residence times slightly over 1 s. The activation energies were determined to be 48.6 kcal/mol for reaction of chloroform with hydrogen and 48.8 kcal/mol for reaction of 1, 1, 2-trichloroethane with hydrogen. © 1986, American Chemical Society.
