Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
84 words
A method of preparing a catalyst comprising reacting an adsorbent solid containing surface hydroxyl groups with a Lewis acid selected from the group consisting of aluminum halides, antimony halides and mixtures thereof in a halogenated organic solvent selected from the group consisting of CCl 4 , CHCl 3 and mixtures thereof at a temperature at atmospheric pressure below about 250° C. and for a time sufficient for said aluminum or antimony halide to react with at least a portion of said surface hydroxyl groups.
Claim 2
Independent Claim
84 words
