Use of low volatility mobile phases in electroosmotic thin-layer chromatography
Autor: B. V. Tyaglov, E. F. Litvin, A. O. Balushkin, Berezkin Viktor G
Publikováno v: Journal of Chromatography A. 1084:13-17
A variant of electroosmotic thin-layer chromatography is suggested with the use of low volatility compounds as mobile phases aimed at drastically decreasing the evaporation of the mobile phase and improving the reproducibility of the method. The line

Autor: Alexander A. Greish, Yu. A. Korolev, M. V. Kopyshev, Leonid M. Kustov, L. M. Kozlova, E. F. Litvin
Publikováno v: Catalysis in Industry. 2:287-289
Glycerol dehydroxylation on a Raney cobalt catalyst in hydrogen was studied. It was found that with an increase in temperature from 140 to 200°C at a hydrogen pressure of 30 MPa, glycerol conversion increases from 14 to 97%. The glycerol is complete

Autor: E. F. Litvin, V. Z. Sharf, S. V. Rusina
Publikováno v: Russian Chemical Bulletin. 42:1200-1203
It has been shown that depending on the catalyst and the solvent used, during the conversion of dibenzyl ether to toluene hydrogenolysis of C-O ether bonds, dehydrogenation and hydrogenolysis of benzyl alcohol formed, hydrogenation and decarbonylatio
