A highly selective process is described for preparingn2,6-dimethylnaphthalene which comprises reacting annaphthalene hydrocarbon selected from naphthalene,nmethylnaphthalenes, dimethylnaphthalenes, trimethylnaphthalenes,npolymethylnaphthalenes or their mixturesnwith one or more benzene hydrocarbons selected fromnbenzene, toluene, xylenes, trimethylbenzenes, tetramethylbenzenes,npentamethylbenzene and/or hexamethylbenzene,nunder at least partially liquid phase conditions,nin the presence of a zeolite belonging to the structuralntype MTW and optionally in the presence of a methylatingnagent. |
