Abstract

Hexa chlorogyclopentadiene is prepd. by introducing in the vapour phase, chlorine and a polychlorocyclopentane of formula C5H8-x Cl2+x (where x is 0-4) into a molten salt of a mixt. of copper chlorides at 250-500 degrees C. The salt melt pref. comprises 10-40% cupric, 30-65% cuprous chloride and 20-50% KCl. No excess chlorine is needed, and the reaction is more efficient in its utilisation of the raw materials with less waste.
