HIGH SELECTIVITY CATALYST FOR THE CONVERSION OF CARBON TETRACHLORIDE TO CHLOROFORM

摘要

A process for the hydrodechlorination of carbon tetrachloride to produce chloroform utilizes a supported catalyst having a bimetallic composition of platinum and iridium. The bimetallic catalyst may be promoted with small amounts of a third metal, such as tin, titanium, germanium, rhenium, silicon, lead, phosphorus, arsenic, antimony, bismuth or mixtures thereof. By-product production is decreased and duration of catalyst activity is improved by the use.
