Benzene → 2-Benzyltoluene

Participants

Reaction Steps

A solution of 70 parts of o-xylyl chloride and 240 parts of benzene is added to a mixture of 135 parts of 80 per cent strength by weight sulfuric acid and 135 parts of 85 per cent strength by weight phosphoric acid at from 75° to 77° C, whilst stirring thoroughly. After a further 5 hours at from 75° to 77° C, 200 parts of water are added, 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.
