Chemistry of Extraction by Sulphoxides
Autor: Yu. E. Nikitin, A.M. Rozen, Yu. I. Murinov
Publikováno v: Russian Chemical Reviews. 45:1155-1166
The present state of the chemistry of extraction equilibria involving sulphoxides of diverse structure — aliphatic, cyclic, and also mixtures of petroleum origin — is discussed, and results are given for the extraction of inorganic and organic ac

Autor: Yu. E. Nikitin, P. F. Nigmatullina, E. G. Galkin, V. P. Krivonogov, V. I. Dronov, I. Kh. Aminev
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 26:1010-1013
1. As a result of modification of the conventional procedure, we obtained bis(2-hydroxyalkyl) sulfides from alkene oxides and monothioethylene glycol with substantially increased yields of the desired product. 2. On dehydration of primary-secondary b

Publikováno v: Analytica Chimica Acta. 148:135-157
A method for preconcentration of platinum metal based on their sorption by a polymeric thioether (—CH2S—)n is reported. The method is characterized by selectivity, high recovery and simplicity, and is suitable for a wide range of platinum meta

Mass-spectrometric study of formation of negative ions by ketosulfide molecules
Autor: I. I. Furlei, V. I. Khvostenko, V. I. Dronov, Yu. I. Murinov, Yu. E. Nikitin
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 32:599-601
The formation of the negative ions of ketosulfide molecules was studied. A redistribution of the excess energy and charge between the keto and sulfide groups occurs in the molecular negative ion formed during electron capture, and the fragmentation i
