Procedure

850 parts of 80 per cent strength by weight sulfuric acid are introduced into a vessel equipped with an impeller stirrer. A solution of 70 parts of o-xylyl chloride and 156 parts of benzene in 200 parts of ligroin are run in at from 75° to 80° C, whilst stirring thoroughly. After a further 5 hours at 80° C, the organic phase is separated off and 75 parts (83% of theory) of o-benzyltoluene boiling at from 97 to 100° C at 0.2 mm Hg are isolated by distillation.
