Abstract

SUPPORTED ACTIVE CUPROUS HALIDE SORBENTS ARE PREPARED BY CONTACTING A CUPROUS HALIDE SOLUTION WITH A POROUS, PARTICULATE SUPPORT, SUCH AS SILICA AND/OR ALUMINA TO IMPREGNATE THE CUPROUS HALIDE THEREIN, THEN CONTACTING THE IMPREGNATED SUPPORT WITH A SUITABLE LIGAND, SUCH AS BUTADIENE, TO FORM A INSOLUBLE COMPLEX WITHIN THE PORES OF THE SUPPORT, AND ACTIVATING THE SORBENT BY DECOMPLEXING THE COMPLEX.
