ABSTRACT:
A process is provided for preparing polymethylbenzenes by simultaneously contacting (a) a phenolic compound, preferably phenol, with (b) a methylating agent, preferably methanol, in the presence of (c) zinc aluminate as catalyst, under such conditions as will result in the at least partial conversion of the reactants to either pentamethylbenzene or hexamethylbenzene or a mixture of both.
