PROCESS FOR THE HYDROHALOGENATION OF AN ALKYNE AND FOR THE MANUFACTURE OF VINYL CHLORIDE BY HYDROCHLORINATION OF ACETYLENE

摘要

Process for the hydrohalogenation of an alkyne and for manufacturing vinyl chloride by hydrochlorination of acetylene in the presence of a catalytic system comprising at least one ionic liquid comprising at least one non-protonated cation, according to which said process is carried out in apparatus made from or covered with materials which are resistant to halogenated acids and more particularly HCl, in dissociated form.
