Abstract

A recirculation procedure for the production of cyclohexanone oxime characterized in that an aqueous reaction medium buffered with an acid reaction containing nitrate and phosphoric acid and/or bisulfate ions, is recirculated between a hydroxylamine synthesis zone and a synthesis zone of cyclohexanone oxime, and in the hydroxylamine synthesis zone the nitrate ions are catalytically reduced with molecular hydrogen in the presence of a palladium catalyst to form hydroxylamine, which hydroxylamine is consumed in the oxime synthesis zone, and the oxime Cyclohexanone is separated from the aqueous reaction liquid, after which this aqueous reaction liquid before being returned to the hydroxylamine synthesis zone is substantially liberated from cyclohexanone and cyclohexanone oxime remaining in a separation process, and the nitrate ions of new contribution required for the synthesis of hydroxylamine are supplied two in the form of nitric acid or nitrous gases; because nitric acid or nitrous replacement gases are supplied after said separation process to remove by distillation the remnants of oxime and cyclohexanone that have been entrained.
