Method for producing alicyclic carboxylic acid and catalyst used in same

摘要

Provided is a method for producing an alicyclic carboxylic acid by hydrogenating an aromatic ring of an aromatic carboxylic acid, which comprises using a catalyst containing ruthenium and palladium as a catalyst, and also provided is a co-supported ruthenium-palladium catalyst in which ruthenium and palladium are present in a form of particles containing both the ruthenium and palladium on a surface of a support. A catalyst has been developed which uses a relatively inexpensive noble metal, ruthenium, which has an activity equivalent to that of a rhodium catalyst, and which does not undergo decrease in activity as observed in a rhodium catalyst, and thereby an industrially simple method for producing an alicyclic carboxylic acid has been established.

1. A method for producing an alicyclic carboxylic acid, the method comprising:
hydrogenating an aromatic ring of an aromatic carboxylic acid in the presence of a catalyst in water, wherein the aromatic carboxylic acid is selected from the group consisting of trimellitic acid, trimesic acid and pyromellitic acid; and the catalyst is a catalyst in which ruthenium and palladium are co-supported on a support.
