19-Nov-2012 | A. G. Vodop’yanov, G. N. Kozhevnikov, Russian Journal of Applied Chemistry, 2012
The possibility of recovering rhenium and osmium from sulfurous gases generated by oxidative roasting of commercial molybdenite product was examined. When passing through solid carbon packing at a temperature in the range 288–380°C, higher rhenium and osmium oxides are adsorbed on the surface of ...
19-Nov-2012 | A. B. Shishmakov, Yu. V. Mikushina, O. V. Koryakova, M. S. Valova, L. A. Petrov, Russian Journal of Applied Chemistry, 2012
The method of the synthesis of dispersed powders of silicon, titanium, and zirconium dioxides was developed, including formation of cellulose inorganic composites by impregnation of pressed granules of powdered cellulose with solutions of tetraethoxysilane and tetrabutoxy zirconium, hydrolysis of ...
19-Nov-2012 | V. M. Farzaliev, E. I. Gasanova, A. I. Akhmedov, Russian Journal of Applied Chemistry, 2012
The synthesis of copolymers of decyl methacrylate with o-allylphenol was performed. The influence of various factors on the results of the process was studied, conditions ensuring producing copolymers with specified characteristics were found. The synthesized copolymers were used to improve the ...
19-Nov-2012 | N. P. Shapkin, L. B. Leont’ev, A. L. Leont’ev, V. V. Korochentsev, A. L. Shkuratov, Russian Journal of Applied Chemistry, 2012
Effect of the composition of chitosan-modified natural silicates on tribotechnical characteristics of additives and formation of a surface layer in friction of surfaces was studied. The following composites were found to be the most promising: 90% serpentine + 10% chitosan-modified vermiculite; ...
19-Nov-2012 | A. F. Gogotov, A. A. Levchuk, L. V. Kanitskaya, Russian Journal of Applied Chemistry, 2012
Mild and low-expenditure method is suggested for synthesis of high-efficiency undesirable-polymerization inhibitors by modification of coke-chemical phenols by treatment with persulfuric acid salts at room temperature under agitation. It is shown that products formed in oxidative combination of ...
19-Nov-2012 | E. N. Shved, M. A. Sinel’nikova, Yu. N. Bespal’ko, N. M. Oleinik, Russian Journal of Applied Chemistry, 2012
The reaction of the anhydride curing epoxy resin ED-20 in the presence of boron trifluoride-amines was investigated in the temperature range 303–393 K. An effect of the basicity of the amine in the complex on the speed of the process was assessed. Based on correlations of a structure of the ...
19-Nov-2012 | S. A. Galadzhev, S. N. Zuev, L. Ya. Tsarik, Russian Journal of Applied Chemistry, 2012
The procedure for preparing spherical particles of copolymers of styrene and technical-grade divinylbenzene in the presence of stabilizers (starch and gelatin) added to improve the process parameters was examined with the aim to develop a process for production of gel ion-exchange resins.
19-Nov-2012 | A. V. Zaichuk, Ya. I. Belyi, Russian Journal of Applied Chemistry, 2012
The possibility and expediency of the application of dump waste open-hearth slag for obtaining ceramic pigments was revealed on the basis of complex physicochemical studies. Ceramic pigments of a brown color gamma were synthesized in the system open-hearth slag-Cr2O3-NiO. The composition of the ...
19-Nov-2012 | G. M. Butov, N. P. Pastukhova, E. A. Kamneva, K. R. Saad, Russian Journal of Applied Chemistry, 2012
New method for synthesis of adamantyl esters of acrylic, methacrylic, and cinnamic acids was developed. The reactions carried out under mild conditions in the absence of catalysts provide a high yield.
19-Nov-2012 | I. V. Pankov, V. P. Yudin, Yu. K. Gusev, V. N. Verezhnikov, Russian Journal of Applied Chemistry, 2012
Low-molecular-weight butadiene and styrene polymers with narrow molecular-weight distribution were prepared by the mechanism of living polymerization with front initiation. Introduction of deactivating nitrogen-containing agents (α-pyrrolidone, N-methylpyrrolildone, caprolactam, urea) into living ...
