Abstract
A process for producing xylene from toluene or benzene by the use as a catalyst of a fluorine-containing crystalline aluminosilicate or a fluorine-containing crystalline borosilicate. The specified crystalline silicate catalyst increases the conversion of toluene or benzen and the selectivity of xylene. This catalyst can keep its high catalytic activity for long periods of time during the reaction.
