Biphenyl → 4-Methylbiphenyl

Participants

Reaction Steps

A process for producing a 4-formyl-4'-methylbiphenyl from a biphenyl which comprises conducting the carbonylation of the biphenyl with carbon monoxide in the presence of a HF-BF3 catalyst in a carbonylation reactor to obtain the resulting reaction product solution containing a 4-formylbiphenyl, separating the 4-formylbiphenyl from the reaction product solution, hydrogenating the separated 4-formylbiphenyl to obtain a 4-methylbiphenyl, recycling the 4-methylbiphenyl to the carbonylation reactor, and then conducting both the carbonylation of the biphenyl with carbon monoxide to obtain a formylbiphenyl and the carbonylation of the 4-methylbiphenyl with carbon monoxide to obtain a 4-formyl-4'-methylbiphenyl simultaneously in the presence of the HF-BF3 catalyst in the carbonylation reactor.
