    摘要： Process for the preparation of 4,4'-diaminodiphenylmethane and its derivatives.4,4'-diaminodiphenylmethane and its derivatives are prepared by the condensation of aniline, or its derivative, and aldehyde, or its precursor and/or isomerization of appropriate intermediate products. The reaction proceeds with zeolites acting as catalysts; these catalysts, which are selected in accordance with the reaction to be effected, are preferably zeolites based on Si, Al and B; Si, Al and Ti; Ti and Fe; ZSM-5; or Y zeolites.

    摘要： A highly selective process is described for preparing 2,6-dimethylnaphthalene which comprises reacting a naphthalene hydrocarbon selected from naphthalene, methylnaphthalenes, dimethylnaphthalenes, trimethylnaphthalenes, polymethylnaphthalenes, and/or their mixtures with one or more benzene hydrocarbons selected from benzene, toluene, xylenes, trimethylbenzenes, tetramethylbenzenes, pentamethylbenzene and/or hexamethylbenzene, under at least partially liquid phase conditions and in the presence of a catalytic composition comprising a zeolite belonging to the MTW structural type and at least one element selected from P, B and Si. The process is preferably carried out in the presence of a methylating agent.
