    摘要: The present invention relates to an integrated process for the production of high purity 2,6-dimethylnaphthalene starting from hydrocarbon mixtures containing naphthalene and/or isomers of methylnaphthalene and/or isomers of dimethylnaphthalene and/or isomers of polymethylnaphthalene, and from an alkylating agent, preferably methanol, reacted in the presence of a methylated benzene solvent or mixture of various methylated benzene solvents, preferably selected from toluene, xylene and trimethylbenzene, and a catalyst consisting of ZSM-12 zeolite and an inorganic ligand.
