Independent Claim
49 words
A dual-function chlorination-condensation catalyst composition consisting essentially of (a) Deacon-type catalyst comprising cupric halide, alkaline earth halide and/or alkali metal halide, and/or rare earth metal halide and (b) crystalline aluminosilicate zeolite component having a silica to alumina ratio of at least 12 and constraint index of 1 to 12.
Claim 2
Dependent Claim
49 words
A dual-function chlorination-condensation catalyst composition consisting essentially of (a) Deacon-type catalyst comprising cupric halide, alkaline earth halide and/or alkali metal halide, and/or rare earth metal halide and (b) crystalline aluminosilicate zeolite component having a silica to alumina ratio of at least 12 and constraint index of 1 to 12.
Claim 3
Dependent Claim
21 words
