Keywords: biodegradability, surfactants, fatty acids, linolenic acid, salts of sulpho acids, petroleum collecting
Pages: 105–111
Anion-active surfactants on the ground of sulpho derivatives of a mixture of fatty acids isolated from corn oil and individual linolenic acid were obtained. Physicochemical properties of surfactants and calcium salts synthesized on their ground have been defined. Research with thin (0.16–0.17 mm) films of petroleum on the surface of various waters (fresh, distilled, sea) has shown that these salts as 5 and 10 % solutions of ethanol possess good petroleum collecting and petroleum dispersing properties. It has been established that 0.025 and 0.05 % solutions of calcium salts are biodegradable.

Experiments on carbothermy of minerals of the sillimanite group (MSG, Al2SiO5, composition (mass %): Al2O3 62.9, SiO2 37.1) and quartzites containing them. The mixture melted after the mechanical activation under reducing conditions. Graphite, charcoal and sawdust were used as reducing agents. Graphite, charcoal and sawdust were used as reducing agents. The average statistical compositions of the products of melting were determined (mass %): aluminium-silicon – Al 93.62, Si 6.14, Fe 0.13, Ti 0.06; n = 429 (n is the number of determinations over which averaging was carried out), in 245 analyses the content of aluminium exceeds 98 mass %; silicon – Si 99.65, Al 0.22, Fe 0.12, Ti 0.02; n = 122. The results of the research show the fundamental possibility of the preparation of silumin, and along the way, silicon from MSG using plasma heating. Resources of the minerals of the group of sillimanite in Russia were evaluated. The program of specific activities on the transition of the production of silumin and aluminium to a new sort of raw materials and new technologies were proposed.

Micro-sized in the cross section aluminum oxide fibres, have been obtained by the sol-gel method with cotton cellulose as a template. The effect of the supramolecular structure of cellulose on the properties of ceramic fibres has been studied. It has been demonstrated that the initial morphology and supramolecular structure of cellulose have a significant impact on the template synthesis process.

New aminoglycosides obtained by the interaction of (1,3,5-trimethyl-1-H-pyrazol-4-yl)methanamine with D-glucose and D-galactose have been characterized. The structure of the class of monosaccharide derivatives studied and their probable stereochemical (anomeric) composition have been established using modern physicochemical research methods (1HNMR and IR spectroscopy). A high growth promoting activity of N-aminoglycoside synthesized has been shown on the example of root formation of common bean.

Pages: 155–160
The method of gas-chemical carbonization of mercury in industrial mercury containing wastes (construction waste and soils) of companies of SC Rosatom with the use of carbon dioxide has been examined. The thermodynamic analysis of the reaction of the formation of divalent mercury basic carbonate (HgCO3 ⋅ 2HgO) at the interaction of mercury oxide with carbon dioxide was performed. The influence of the pressure of carbon dioxide, temperature and treatment time on the effect of gas-chemical carbonization of mercury oxide was studied. The technological scheme of the two-stage gas chemical recycling of mercury-containing wastes has been proposed. Biotesting of samples of construction waste and soils subjected to gas-chemical carbonization of mercury has been held.

A method for the synthesis of the application material for medical purposes based on the carbon hemosorbent is described. The chemical modification of a carbon material was performed via impregnation by azobisisobutyric acid dinitrile (DINIZ) in monomer N-vinylpyrrolidone (VP) with the subsequent polymerization. Selecting the optimal parameters of the modification that allow applying up to 8–15 mass % of poly-N-vinylpyrrolidone (PVP) onto the carbon sorbent is described in detail. As the general analysis we used a thermal method that provides monitoring the VP polymerization process on the carbon material. The proposed method for the synthesis of PVP on the surface of the carbon sorbent was compared with alternative methods of PVP preparation on the surface of different nature carriers. The analysis of the physicochemical properties of the studied sorbents is presented. The reported results of microbiological studies have demonstrated the possibility of using carbon sorbents for the vulnerosorption.
