Abstract

A process for preparation of adipinic acid by oxidation of cyclohexanol or cycloxaxanol and cyclohexanon mixture by nitric acid in the presence of copper-vanadium catalyst provides re-circulation through the oxidation reactor of 90-93 % reaction mixture, separated from nitric oxides by means of blowing up and vacuumizing. The invention relates to chemical technology.
