Process for para selective alkylation of aromatic hydrocarbons
Patent
·
OSTI ID:5398413
A process is described for the selective alkylation of monoalkylbenzene into dialkylbenzenes wherein the para isomer of the disubstituted product is present in a concentration greater than in an thermodynamic equilibrium, comprising: passing the monoalkylbenzene and an alkylating agent capable of methylation, ethylation or propylation under conversion conditions through a reaction zone containing an unmodified crystalline silica catalyst of the silicalite type having the monoclinic symmetry.
