Title:
PRODUCTION OF 3-HYDROXYMETHYL-1,6-HEXANEDIOL
Document Type and Number:
Japanese Patent JP3915153
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain hydroxymethylhexanediol that is useful for epoxy resin in high yield under milder temperature and pressure conditions by catalytically hydrogenating butanetricarboxylic acid (trialkyl ester) in liquid phase in the presence of Ru or the like on a carrier catalyst.
SOLUTION: 1,2,4-Butanetricarboxylic acid (trialkyl ester) is catalytically hydrogenated in liquid phase, for example, in water in the presence of a catalyst on a carrier, for example, Ru, Pt or Sn on carbon activated with nitric acid at 100-250°C and a pressure of 1-35MPa to prepare 3-hydroxymethyl-1,6- hexanediol. This hydrogenation is preferably carried out in the presence of a cocatalyst selected from oxides and hydroxides of alkali metal and alkaline earth metal, salts of alkali metal and alkaline earth metal and nitrogen containing bases and their salts.
