摘要:
In a process for the production of adipic acid by nitric acid oxidation of cyclohexanol and/or cyclohexanone wherein copper and vanadium values are recovered by ion exchange means, the improvement which comprises utilizing the off-gas from the nitric acid oxidation to treat the solution being passed to the ion exchange zone.
