- PROCESS FOR THE PURIFICATION OF A MIXTURE COMPRISING N-ALKYL-HYDROXYLAMMONIUM SALTS
-
The present invention relates to a process for purification of a mixture comprising water, N-alkyl-hydroxylammonium salts and some byproducts wherein from the mixture water and byproducts are distilled off until the purity of N-alkyl-hydroxylammonium salts in the residue is 95% or higher and additionally keeping the water content during and after the distillation ≥ 40 wt.-% according to the residue.

- Molybdenum(VI) complexes with N-substituted hydroxylamines
-
New molybdenum(VI) complexes with N-monoalkylsubstituted hydroxylamines have been synthesized and studied. The structure of [MoO2(C 2H5NHO)2] and [MoO2(i-C 3H7NHO)2], whose distinguishing feature is the bidentate chelate coordination of the ligand to molybdenum with the formation of the three-membered NMoO chelate ring, has been determined by X-ray diffraction.

- Process for obtaining N-monosubstituted hydroxylamine
-
The subject of the present invention is a new process for obtaining nitrones. It more particularly relates to a process for obtaining N-monosubstituted hydroxylamine comprising a stage in which a nitrone is formed from a secondary amine in the presence of an oxidizing agent and of at least one C=O containing species chosen from the group consisting of carbon dioxide, hydrogencarbonates and carbonates.
