Abstract
Procedure for the simultaneous obtaining of ammonium sulphate and lactams from mixtures obtained by transposition of Beckmann of cycloaliphatic ketoximes with sulfuric acid or oleum, using ammonia for the neutralization of the reaction mixture and operating with concentrations that do not allow separation - by precipitation of solid ammonium sulfate during the neutralization, then separating the aqueous layer of crude lactam from the ammonium sulfate solution, extracting the crude lactam layer with at least the triple amount of benzene and finally distilling the benzene lactam solution separated from the aqueous phase, characterized in that a solution of ammonium sulphate, especially a mother liquor of ammonium sulphate obtained in another previous operation, is added to the transposition mixture, before or during the neutralization, to evaporate part of the water contained in the ammonium sulfate solution obtained after removing the cap a of raw lactam, separate the crystalline arsenic sulfate obtained in pure form, and recirculate the mother liquor obtained in this process, to the neutralization zone, possibly after diluting it with water.
