Date Jul. 14, 1988.The object of the invention is a catalyst system for selective alkylation of toluene with propylene. The catalyst system contains metallic sodium which has been thermally decomposed from sodium azide (NaN3) or sodium oxide (Na2O) onto the surface of solid K2CO3. The invention further concerns a procedure for preparing this catalyst system and a procedure for selectively alkylating toluene with propylene in the presence of a catalyst system. |
