Procedure

A solution of 70 parts of o-xylyl chloride and 240 parts of benzene is added to a mixture of 250 parts of 75 percent strength by weight sulfuric acid and 30 parts of zinc chloride at from 75° to 80° C, whilst stirring thoroughly. After a further 6 hours, the organic phase is separated off and 80 parts (88.9% of theory) of o-benzyltoluene boiling at 98° C at 0.2 mm Hg are isolated by distillation.
