摘要：Adipic acid is prepared from cyclohexanone by contacting with molecular oxygen in the presence of a maganese or manganese/copper catalyst at reaction temperatures in the range 60 to 90 DEG C. which increase in stages. The cyclohexanone feedstock may be obtained from the oxidation of cyclohexane and may be admixed with cyclohexanol. Manganese acetate which may be admixed with copper acetate may be used as the catalyst in acetic acid, a saturated carboxylic acid (2-6 C atoms) cholorobenzene or t-butyl alcohol, as the reaction medium. Temperature stages mentioned are 65-75 DEG C. for 1 to 4 hours and 75 to 85 DEG C. for the remainder of a period of 7 hours.
