Abstract

Process in which olefins are substantially removed from an acetylenic and olefin-contg. gaseous hydrocarbon mixture by chlorinating the mixture in the presence of the liquid chlorination products of the mixture at below 60 degrees C. The process is conducted in a novel reactor. The resulting gaseous product is useful as a welding and cutting gas.
