Results of thermodynamic calculations and kinetic studies of the reaction of zinc ferrite ZnFe2O4 and of a mixture of oxides, ZnO and Fe2O3, with chlorine and SO2 are presented.
Stability of sodium borohydride in the form of concentrated solutions and suspensions and solids corresponding to a crystal hydrate in composition was studied. The effects of temperature, concentrations of sodium borohydride and alkali, and nature of alkali metal cation on the rate of sodium...
Modern concepts of thin-layer chromatography of macromolecular compounds are reviewed, including the features and potentialities of thin-layer size-exclusion chromatography.
A combined method for no-standard determination of zinc in aqueous solutions (calibration of the device against standard solutions or use of standard additions is not required) is suggested. The method is based on principles of stripping voltammetry and potentiostatic coulometry.
The linear dependence of the retention factor of indole, imidazole, triazole, and tetrazole derivatives on the acetonitrile content of the mobile phase was studied.
The organic extracts formed in joint extraction of vanadium(V) and vanadium(IV) with di(2-ethylhexyl) hydrogen phosphate from weakly acidic aqueous solutions were characterized by IR and electronic spectroscopy and chemical analysis.
Electroreduction of oxygen in gas-diffusion hydrophobized porous electrodes containing 8–10 wt % fluoroplastic, made of expanded natural graphite and acetylene black, in acidic (pH 0.6) and alkaline electrolytes was studied.
Procedures for esterification of biologically active mono-and bispiperidols by reactions with benzoyl and terephthaloyl chlorides were developed.
A series of quaternary bisammonium salts containing the common 5-oxanonane-2,7-diyne-1,9-diyl fragment and different alkoxycarbonylmethyl groups was synthesized. The surfactant properties and antimicrobial activity of these compounds were studied.
Possibility of obtaining rigid foamed polyurethanes filled with aluminosilicate microspheres was analyzed. The physicomechanical and rheological properties of these composites were studied.
