Abstract

Hydrogen chloride is purified by the catalytic reduction of small amounts of acetylene with added hydrogen, present in an amount greater than one mole of hydrogen per mole of acetylene, at a temperature above 50 DEG C and at a space velocity (as defined in the Specification of 300-5000. The catalyst may be either platinum or palladium or an oxide thereof and may be supported or unsupported. The preferred conditions are a temperature of 60-400 DEG C., particularly 125-175 DEG C., a pressure of 20-100 p.s.i.g., a molar ratio of hydrogen to acetylene of 2.5 to 3.5 and a space velocity of 1500-3500. The hydrogen added may contain up to 50% by volume of an inert diluent such as methane or nitrogen. The catalyst converts the acetylene to ethylene together with some ethane but no vinyl chloride is produced.ALSO:Vinyl chloride and hydrogen chloride are produced by cracking 1,2-dichloroethane at an elevated temperature, acetylene impurity formed in the hydrogen chloride is removed as described below and the resulting hydrogen chloride is used to produce more 1,2-dichloroethane by contacting it with ethylene, oxygen and a fluidized copper containing catalyst under pressure at 200-250 DEG C. Acetylene contained in the hydrogen chloride vapour is catalytically reduced by hydrogen, present in an amount greater than one mol. of hydrogen per mol. of acetylene, at a temperature greater than 50 DEG C. and at a space velocity (as defined in the Specification) of 300-5000 to form ethylene together with a minor proportion of ethane but no vinyl chloride is formed. The preferred catalyst is platinum or palladium or oxides thereof and may be supported or unsupported.
