Abstract
A procedure for the conversion of a mixture of aromatic compounds having eight carbon atoms, said mixture containing ethylbenzene and xylenes, to isomerize the xylenes contained in said mixture and convert at least part of the ethylbenzene contained in it to xylene or compounds that can it is easily separated by distillation of the aromatic compounds of eight carbon atoms, a procedure that comprises contacting said mixture with a catalyst that comprises a zeolite of the ZSM-5 type, zeolite ZSM-12 or zeolite ZSM-21, in the vapor phase and a temperature of 259.7ºC to 537.2ºC.
