<P>PROBLEM TO BE SOLVED: To provide a technique for producing 1,6-hexanediol at a low cost by using cyclohexanone as a starting raw material. <P>SOLUTION: In the method, 1,6-Hexanediol is produced by a catalytic reduction reaction of a crude ε-caprolactone fraction obtained from a reaction process of an organic peracid and/or hydroperoxide with cyclohexanone or a by-product fraction composed mainly of residual ε-caprolactone left after separating ε-caprolactone from the crude ε-caprolactone, by-produced oxycaproic acid, adipic acid and their oligomers as they are in the presence of a hydrogenation catalyst or after esterifying the fraction with an alcohol. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
