Sulfuric Acid → 2-Benzyltoluene

Participants

Reaction Steps

A solution of 70 parts of o-xylyl chloride in 230 parts of benzene is added to 350 parts of 75 per cent strength by weight sulfuric acid at 80° C in a stirred vessel, the mixture being stirred with an impeller stirrer at 900 revolutions per minute. After a further 5 hours at 80° C, during which the batch is mixed thoroughly, the organic phase is separated off and 73 parts (= 81.1% of theory) of o-benzyltoluene boiling at from 97° to 100° C at 0.2 mm Hg, and of nD25 = 1.5749, are isolated by distillation.
