Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A process for the oxidation of hydrocarbons which comprise contacting an unsubstituted C 3 -C 16 saturated or mono-unsaturated hydrocarbon selected from the group consisting of alkanes, alkenes, cycloalkenes and polycycloalkanes with oxygen or air at temperatures of from 25° to 200° C in the presence of a catalyst comprising a copper polyphthalocyanine and an aromatic heterocyclic amine, said amine being selected from the group consisting of pyridine, quinoline, isoquinoline, triazine, and pyrazine, wherein the weight ratio of amine to copper polyphthalocyanine is between 0.7:1 and 2:1.
Claim 2
Dependent Claim
87 words
