Abstract
Abstract Anthranilic acid has been anchored to polystyrene, and rhodium, palladium, platinum and ruthenium complexes of this modified polystyrene have been prepared. These catalysts will reduce a variety of olefinic and aromatic hydrocarbons, and also nitrile, nitro and carbonyl functional groups, said carbonyl groups being present in either ketones or aldehydes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
A process for the catalytic hydrogenation of organic compounds which comprises reacting said compounds with hydrogen in the presence of a heterogeneous catalyst consisting essentially of anthranilic acid complexed with a member selected from the group consisting of rhodium, ruthenium, palladium and platinum, said anthranilic acid complex being chemically linked through the amino group thereof to a polymeric support having reactive sites thereon for effecting the chemical linkage between the anthranilic acid complex and said polymer.
Claim 2
Dependent Claim
76 words
A process for the catalytic hydrogenation of organic compounds which comprises reacting said compounds with hydrogen in the presence of a heterogeneous catalyst consisting essentially of anthranilic acid complexed with a member selected from the group consisting of rhodium, ruthenium, palladium and platinum, said anthranilic acid complex being chemically linked through the amino group thereof to a polymeric support having reactive sites thereon for effecting the chemical linkage between the anthranilic acid complex and said polymer.
