| titleOfInvention | Method for esterifying carboxylic acid-containing mixture obtained from cyclohexane oxidation reaction solution and 1,6-hexanediol obtained from the ester mixture |
| abstract | To obtain 1,6-hexanediol in a high yield from a carboxylic acid-containing mixture separated and recovered from a liquid-phase oxidation reaction solution of cyclohexane, and to monoesterify the carboxylic acid-containing mixture with a monoalcohol ester The aim is to develop a method. SOLUTION: When separating cyclohexanol and cyclohexanone from an oxidation reaction solution obtained by subjecting cyclohexane to liquid phase oxidation, and subjecting the recovered carboxylic acid-containing mixture to an esterification reaction, (1) In the presence of a strongly acidic solid catalyst having an acid strength of H 0 (Hammet's acidity function) of −3 or less, (2) gaseous lower monoalcohol; (3) bringing the above-mentioned carboxylic acid-containing mixture into countercurrent contact; This is solved by a method for esterifying a carboxylic acid-containing mixture, which is characterized in that the 1,6-hexanediol can be obtained in a high yield by hydrogenolyzing the esterified mixture obtained by the method.
