Process for preparing 1-chloro-1,3-butadiene
摘要:
Process for preparing 1-chloro-1,3-butadiene, which consists in gas-phase dehydrochlorinating a dichlorobutene selected from 3,4-dichloro-1-butene and 1,4-dichloro-2-butene, in the presence of a catalyst selected from lanthanum phosphate and lanthanum phosphate doped with an alkali or alkaline-earth metal.
