Title:
METHOD FOR PRODUCING HYDROGENATED AROMATIC POLYCARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP2006083080
Kind Code:
A
Abstract:

To provide a method for producing a hydrogenated aromatic polycarboxylic acid, by which the highly pure hydrogenated aromatic polycarboxylic acid can profitably be produced in a high yield, and to provide the hydrogenated aromatic polycarboxylic acid substantially not containing an aromatic polycarboxylic acid of raw material.

This method for producing the hydrogenated aromatic polycarboxylic acid, comprising subjecting the aromatic polycarboxylic acid to a nucleus hydrogenation reaction in the presence of a reaction solvent and a nucleus hydrogenation catalyst, is characterized in that the catalyst is a rhodium-γ-alumina-carrying catalyst obtained by carrying a rhodium metal on a γ-alumina carrier; the specific area of the carrier is 50 to 450 m2/g; and the amount of the rhodium metal in the catalyst is 0.25 to 0.5 pt. wt. per 100 pts. wt. of the aromatic polycarboxylic acid.
