Toluene and dry bleaching powder are heated together to 105 degrees in the abscence of other reagents.This avoids by-product formation. If equal amts are used, volume-wise, there is a high conversion. If more bleaching powder is used, the conversion is more robust, but contaminants such as benzal chloride and benzotrichloride are formed...

What is "bleaching powder"? It must contain chlorine, is it PbCl2?
