ABSTRACT:
A catalyst consisting essentially of cuprous chloride intercalated in crystalline boron nitride, containing at least 10% copper, useful for substitution chlorination of organic substances in vapor phase at elevated temperature by action of chlorine or HCL and oxygen. Highly selective for chlorination versus oxidation and hydrolysis even at high conversions, using partially chlorinated organic material as reactant, in particular methyl chloride.
