ABSTRACT:
A process for the manufacture of adipic acid is disclosed. In this process, cyclohexane is oxidized in an aliphatic monobasic acid solvent in the presence of a soluble cobalt salt wherein water is continuously or intermittently added to the reaction system after the initiation of oxidation of cyclohexane as indicated by a suitable means of detection, and wherein the reaction is conducted at a temperature of about 50.degree. C. to about 150.degree. C. at an oxygen partial pressure of about 50 to about 420 pounds per square inch absolute.
