Synthesis of Phthaloyl chloride

A reflux apparatus equipped with a calcium chloride drying tube is set up, whereto 60.2 g of phthalic anhydride, 84.1 g of benzotrichloride and 3.2 g of hydrated zinc chloride. The mixture is agitated and refluxed at 120-130°C for 12 h, the mixture is then fractionally distilled to obtain benzoyl chloride at 82-84°C and phthaloyl chloride at 132-136°C.
