Sulfuric Acid → 2-Benzyltoluene

Participants

Reaction Steps

A solution of 70 parts of o-xylyl chloride and 200 parts of benzene is added in the course of 2 hours, whilst stirring thoroughly, to a mixture of 250 parts of 70 per cent strength by weight sulfuric acid and 72 parts of phosphorus pentoxide at from 75° to 77° C. After a further 4 hours at from 75° to 77° C, the organic phase is separated off and 80.9 parts (89.8% of theory) of o-benzyltoluene boiling at 98° C at 0.2 mm Hg are isolated by fractional distillation.
