    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.
