Procedure
A mixture of 294 grams (2.0 moles) of paradichlorobenzene, 819 grams (3.0 moles) of hexachlorocyclopentadiene, and 15 grams of aluminum chloride, in 300 grams of perchloroethylene was heated at 80°-92° centigrade for two hours during which time a total of 103 grams of hydrogen chloride was evolved. Ten milliliters of water and 20 grams of Superfiltrol absorbent were added and the reaction mixture was stirred at 60° centigrade for 30 minutes and then filtered with suction. The filtrate was distilled at reduced pressure and the fraction boiling at 131°-160° centigrade at 0.5 to 2.3 millimeters of mercury pressure was collected and refractionated through a one foot long heated Vigreux column to give pure 2,4-dichlorophenyl pentachlorocyclopentadiene as a pale yellow viscous oil of boiling point of 146°-147° centigrade at 0.4-0.6 millimeters of mercury.
