ABSTRACT:
A process for the hydrodechlorination of carbon tetrachloride to produce chloroform and methylene chloride utilizes a supported platinum catalyst that is subjected to chloride pre-treatment. The platinum catalyst may be promoted with small amounts of metals such as tin. By-product production is decreased and duration of catalyst activity is improved by the process of this invention.
