Process for the manufacture of chloroform

A process for manufacture of chloroform by catalytic hydrogenolysis of carbon tetrachloride, comprising the steps of reacting liquid carbon tetrachloride with a hydrogen-containing member selected from the group consisting of hydrogen gas and gases containing molecular hydrogen at a pressure below 8,000 kPa and at a temperature below 250.degree. C., in the presence of a catalyst, said catalyst comprising a metal deposited on a powdered substrate, and said catalyst being held in suspension in the liquid carbon tetrachloride, said metal being selected from the group consisting of palladium, rhodium, ruthenium and platinum, and wherein the catalyst and the liquid carbon tetrachloride are present in a weight ratio of from 0.1/100 to 5/100 during the reacting.
