Yeo, G. A.,Ford, T. A.
, p. 307 - 324 (1990)
The infrared spectra of the hydroxylamine monomer and dimer, trapped in nitrogen and argon matrices at ca. 17 K, have been obtained.Assignments have been made, based on concentration and matrix diffusion experiments, and the wavenumber shifts arising from

The invention discloses a joint production technology of hydroxylamine, hydroxylammonium salt and cyclohexanone-oxime. The material comprises the steps that reaction liquid obtained by raw materials through an ammoximation reaction and a hydrooximation reaction is extracted and separated to obtain an organic phase, the organic phase is prepared into product cyclohexanone-oxime, or part of the organic phase and part of product cyclohexanone-oxime are adopted as raw materials for an oxime hydrolysis reaction to be hydrolyzed, the organic phase in hydrolysis liquid is circulated to return to a oximation reactor, part of an inorganic phase in the hydrolysis liquid is adopted as a raw material to be circulated to return to a hydroxylamine oximation reactor, and the other part of the inorganic phase is prepared into a hydroxylamine aqueous solution and hydroxylammonium salt. The joint production technology of hydroxylamine, hydroxylammonium salt and cyclohexanone-oxime is simple in procedure, the requirement of the ammoximation reaction for the purity of the raw material cyclohexanone and the catalyst performance is lowered, a high quality cyclohexanone-oxime product without cyclohexanone is obtained, the simplification of the downstream caprolactam technology and the improvement of the product quality are benefited, and the hydroxylamine and hydroxylammonium salt product which have high additional value are obtained simultaneously.

Page/Page column 4-5, (2008/12/06)
A recycling system for hydroxylamine formation and oximation is proposed. The recycling system includes a hydroxylamine formation zone, an oximation zone, a purification zone, and an adjusting zone having a nitrate absorption tower. An inorganic process s
