Abstract
IMPROVEMENTS INTRODUCED IN THE PURPOSE OF MAIN PATENT No. 386.192, requested on December 4, 1970, for "A recirculation procedure for the production of cyclohexanone oxime" according to which an improved cyclic procedure, in which an aqueous reaction medium, acid-reacted, damped, containing phosphoric acid and/or bisulfate, in addition to nitrate ions, is maintained in circulation between a hydroxylamine synthesis zone and a cyclohexanone oxime synthesis zone and in which, in the Hydroxylamine synthesis zone, nitrate ions are catalytically reduced with molecular hydrogen in the presence of a palladium catalyst, and, before the circulating liquid enters the hydroxylamine synthesis zone, the circulating liquid is subjected to a temperature sufficiently high and in a sufficiently long residence time, to a heat treatment, in such a way that the sum of the contents of cyclohexanone and of the oxime of cyclohexanone, present at first as impurities, it decreases; whose improvements are characterized by the fact that the thermal treatment takes place in the presence of nitrous acid at a temperature of at least 50ºC.
