<p>PURPOSE:To provide a production method capable of high selectively producing 4-methylbiphenyl and 4,4'dimethylbiphenyl each in a high yield, of readily regenerating the catalyst without requirement for a special aftertreatment of the reaction products and of carrying out the reaction continuously. CONSTITUTION:This method for production of 4-methylbiphenyl or 4,4'- dimethylbiphenyl is carried out by a transalkylantion reaction of biphenyl or 4-methylbiphenyl using a polymethylbenzene or a polymethylnaphthalene in the presence of a solid acid catalyst containing a fluorine-treated silica alumina or a zeolite having >=0.7nm pore size.</p> |
