摘要：
A process for the selective alkylation of monoalkylbenzene into dialkylbenzenes wherein the para isomer of the disubstituted product is present in a concentration greater than in a thermodynamic equilibrium is provided. The method comprises passing the monoalkylbenzene and an alkylating agent capable of methylation. ethylation or propylation through a reaction zone containing an unmodified crystalline silica catalyst of the silicalite type having the monoclinic symmetry.
