Abstract: Production of an aqueous solution of hydroxylammonium nitrate by catalytic reduction of nitrogen monoxide with hydrogen in acid solution, a platinum catalyst being used which has been partly poisoned with one or more elements of main groups V and/or VI of the Periodic Table and activated prior to the beginning of the reaction in an aqueous suspension with hydrogen. Nitric acid is continuously supplied during the reaction in an amount necessary for the end concentration of hydroxylammonium nitrate.

Abstract: A process for the production of cycloalkanone oximes by reaction of cycloalkanones with hydroxylammonium salts or mixtures thereof with ammonium salts and acids in aqueous solution. The free and combined acid is removed from the mixtures by electrodialysis before, during or after the oximation. The reaction of the cycloalkanone to the oxime is preferably carried out in the cathode chamber of an electrodialysis cell. Complete oximation of the cycloalkanone is achieved.

Abstract: Caprolactam is recovered from a mixture which contains caprolactam and oligomers of the same by distillation at temperatures above the melting point of the oligomers or mixture thereof contained in the residue at atmospheric or slightly increased pressure. The process is of importance for removing residues of caprolactam oligomer residues and thus for effluent pollution control.

Abstract: Production of aliphatic and cycloaliphatic Alpha -nitroketones in liquid phase by reaction of the corresponding ketones with concentrated nitric acid whose water content is less than 5.0 percent by weight. In principle all aliphatic and cycloaliphatic ketones can be nitrated according to the invention. Examples are diethyl ketone, cyclohexanone and cyclododecanone.
