The invention relates to a process for preparing 1,6-hexanediol and caprolactone, preferably with at least 99.5% purity, which are especially virtually free of 1,4-cyclohexanediols, from a carboxylic acid mixture which is obtained as a by-product of the catalytic oxidation of cyclohexane to cyclohexanone/cyclohexanol with oxygen or oxygen-comprising gases and by water extraction of the reaction mixture, by hydrogenating the carboxylic acid mixture, esterifying and hydrogenating a substream to hexanediol and cyclizing 6-hydroxycaproic ester, the 1,4-cyclohexanediols being removed either in the course of fractionation of the esterification mixture or last from the caprolactone.

Processes process for producing adipate or adipic acid using biological pathways and chemical catalyzes are disclosed. Homocitric acid may be a substrate in reaction pathways leading to adipic acid or a salt thereof.
The present invention is a method of producing ε-caprolactam through adipamide as an intermediate, and characteristically includes a lactamization step of reacting adipamide, formed from a material compound, with hydrogen and ammonia in the presence of a catalyst containing: a metal oxide mainly containing an oxide(s) of one or more metallic elements selected from the group consisting of metallic elements of group 5 and groups 7 to 14 in the 4th to 6th periods of the periodic table; and a metal and/or a metal compound having a hydrogenation ability. The method can increase the selectivity of ε-caprolactam.
