ABSTRACT:
A catalytic process is provided for the selective production of pseudocumene and durene by contacting a hydrocarbon feed containing benzene or a methyl substituted benzene under methylating conditions and in the presence of a methylating agent with a catalyst comprising AMS-1B crystalline borosilicate. In the resulting product pseudocumene and durene are obtained in selectivities higher than equilibrium concentrations of respectively trimethylbenzenes and tetramethylbenzenes.
