Patent ID: 8846973

Claim:
A method of producing a hydrogenated product of aromatic polycarboxylic acid, the method comprising: producing the hydrogenated product of the aromatic polycarboxylic acid by hydrogenating an aromatic ring of the aromatic polycarboxylic acid in the presence of a catalyst, wherein: (1) the catalyst is a supported catalyst comprising rhodium in combination with palladium supported on a carbon support; (2) the rhodium is present in an amount of 0.05 part by weight or more and less than 0.5 part by weight per 100 parts by weight of the aromatic polycarboxylic acid; (3) the palladium is present in an amount of 0.5 part by weight or more and less than 5.0 parts by weight per 100 parts by weight of the aromatic polycarboxylic acid; (4) a hydrogen partial pressure is 1.0 to 15 MPa; (5) a reaction temperature is 30 to 80° C.; and (6) the aromatic polycarboxylic acid is dissolved or suspended in a reaction solvent.
