PURIFICATION OF ANHYDROUS HYDROGEN CHLORIDE

摘要

A method to purify impure gaseous hydrogen chloride containing unsaturated chlorinated hydrocarbons in an amount less than that necessary to inhibit purification comprising exposing the impure hydrogen chloride to an ultraviolet light source in the presence of gaseous chlorine for a sufficient time for the gaseous chlorine to react with organic impurities in the hydrogen chloride to form heavier organic compounds and thereafter separating the heavier compounds from the hydrogen chloride. 36,384-F
