摘要： A composition comprising a copper(I) impregnated aluminosilicate zeolite wherein the zeolite is selected from faujasites, L and .OMEGA., and wherein the zeolite has a silica to bulk alumina molar ratio between about 12 and about 50 and a silica to framework alumina molar ratio of at least about 15. The catalyst preparation involves in the following order: drying the selected zeolite, impregnating the dried zeolite with a copper(II) salt, calcining the copper(II)-impregnated zeolite, and reducing the copper(II) to copper(I). The composition is useful as a catalyst for the cyclodimerization of 1,3-butadiene to 4-vinylcyclohexene.

摘要： The invention, in one aspect, is a process for preparing a (methyl-substituted)diphenyl methane by coupling at least (including benzene) a methyl-substituted benzene into the (methyl-substituted)diphenyl methane comprising contacting at least the methyl-substituted benzene with a solid heterogeneous reactant-catalyst having labile oxygen under conditions whereby the (methyl-substituted)diphenyl methane is prepared. For example, using molybdenum trioxide or vanadium pentoxide, toluene can be coupled in the vapor or liquid phase to prepare (2-methylphenyl)phenylmethane. By-product formation, especially formation of carbon dioxide, can be very low.

摘要： A (methyl-substituted)diphenyl methane such as methyldiphenylmethane is prepared by a coupling reaction wherein a methyl-substituted benzene such as toluene is contacted with a solid heterogeneous catalyst having labile oxygen such as an oxide of vanadium, rhenium or molybdenum. By-product formation, especially the formation of carbon dioxide, is significantly reduced by the practice of this process.
