Title:
METHOD FOR PRODUCING ALICYCLIC CARBOXYLIC ACID AND CATALYST USED IN SAME
Document Type and Number:
WIPO Patent Application WO/2012/117976
Kind Code:
A1
Abstract:
Provided are a method for producing an alicyclic carboxylic acid by hydrogenation of the aromatic ring of an aromatic carboxylic acid, wherein a catalyst containing ruthenium and palladium is used as the catalyst, and a catalyst supporting both ruthenium and palladium wherein ruthenium and palladium are supported, on the supporting surface, in the form of particles containing both ruthenium and palladium. An industrially simple method for producing an alicyclic carboxylic acid was realized upon discovering a catalyst that uses ruthenium, which is a relatively inexpensive noble metal, to obtain the same activity as with a rhodium catalyst but without the reduction in activity seen with a rhodium catalyst.
