ABSTRACT:
A process for the cyclodimerization of 1,3-butadienes to 4-vinylcyclohexenes. The process involves contacting butadiene with a copper (I)-aluminosilicate zeolite prepared by (a) an impregnation method, or (b) heating a solid mixture of a copper salt and the zeolite, or (c) contacting vapors of a copper salt with the zeolite. The catalysts exhibit long life and good activity in the claimed process. The impregnated Cu(I)-catalyst is claimed.
