A highly selective process is described for preparing 2,6-dimethylnaphthalenenwhich comprises reacting a naphthalenenhydrocarbon selected from naphthalene, methylnaphthalenes,ndimethylnaphthalenes, trimethylnaphthalenes, polymethylnaphthalenes,nand/or their mixtures with one or more benzenenhydrocarbons selected from benzene, toluene, xylenes,ntrimethylbenzenes, tetramethylbenzenes, pentamethylbenzenenand/or hexamethylbenzene, under at least partially liquidnphase conditions and in the presence of a catalytic compositionncomprising a zeolite belonging to the MTW structuralntype and at least one element selected from P, B and Si.nThe process is preferably carried out in the presence of anmethylating agent. |
