Versuchsvorschrift

α-trichloromethyl-p-chlorobenzyl alcohol, 5.0g, was stirred with p-chlorophenol, 2.6g, and sulfuric acid, 35 ml, was added dropwise. After 2 hrs. of stirring, the mixture was poured onto ice and extracted with ether. After drying with sodium sulfate, the ether was removed under vacuum and the residue was recrystallized from ethanol to give α-trichloromethyl-p-chlorobenzyl p-chlorophenyl ether, mp 101°C. This method of synthesis is referred to in Table I as method A.
