Process for alkylating or alkylating-transalkylating a charge containing toluene, methanol and, optionally, polymethylbenzenes, in one or two steps, conducted at a temperature from 100 DEG to 600 DEG C under a pressure from 1 to 150 bars in the presence of hydrogen and of a catalyst having a zeolite base of the faujasite type selected from Y sieves containing less than 2% by weight of sodium and at least 0.5% by weight of nickel, silver, cadmium or a mixture thereof and in which the molar ratio SiO2/Al2O3 is from 2 to 6, and also in the presence of sulfur either introduced into the charge or preintroduced into the catalyst or both. |
