Processes occurring in a cycled nickel-zinc battery with positive nickel oxide electrode fabricated from spherical nickel hydroxide on foamed-nickel support and the influence exerted by its physicochemical parameters on changes in the electrolyte composition and on inter- and intraelectrode mass transfer of zinc was studied. 相似文献

Acid-base and complexation properties of gem-disubstituted phosphorus acids, viz., methylenediphosphonic, 1-hydroxyethylidene-1,1-diphosphonic, P,P-diphenylmethylene-diphosphinic, and P, P-diphenyl-1-hydroxyethylidene-1, 1-diphosphinic acids, were studied in aqueous solutions and in the presence of biomimetics (micelles of ionic surfactants). The dissociation constants of the acids and stability constants of complexes with magnesium(II) and copper(II) ions were determined in aqueous solutions and microheterogeneous media containing sodium dodecyl sulfate, cetylpyridinium chloride, or cetylpyridinium nitrate (ionic strength 0.1 mol L–1, temperature 25°C).Published in Russian in Izvestiya Akademii Nauk.

The reaction of nitrates (nitro esters) of amino alcohols with alkali metal hydrogen carbonates yielding oxazolidin-2-ones and tetrahydro-1,3-oxazin-2-ones was discovered. A large number of both known and newly synthesized nitrates of amino alcohols with various structures were involved in this reaction, and the optimum reaction conditions were found. New oxazolidin-2-ones and tetrahydro-1,3-oxazin-2-ones were synthesized. Two more transformations were found for a few examples. One of the reactions gives nitramino alcohols, whereas another reaction affords polymers. 相似文献

The possibilities of isocratic separation of 2,4-dinitrophenyl derivatives of 12 amino acids that considerably differ in hydrophobicity by micellar mobile phases with different organic modifiers have been discussed. For the first time aliphatic carboxylic acids have been used as modifiers of micellar eluent in micellar liquid chromatography with C18 columns. Elution strength of hybrid micellar phases on the basis of sodium dodecylsulfate and aliphatic carboxylic acids increases in sequence: acetic相似文献

The complex dielectric permittivity in the frequency range 7.5–25.0 GHz and the low-frequency specific conductivity of aqueous solutions of diallylammonium salts (diallylammonium and diallylmethylammonium trifluoroacetates and diallyldimethylammonium chloride) were measured at 293–308 K over a wide concentration range. On the basis of the results, the parameters of dielectric relaxation were calculated. The number of water molecules in the solvation shell of the salts was estimated. The concentration behavior of the initial rate of radical polymerization of diallylammonium salts and the rate constant of bimolecular chain termination was correlated with the specific features of the structure of aqueous monomer solutions. The role of “free” water in the initial salt solutions was revealed, a species whose presence in the system determines the character of concentration behavior of the rate constants for the elementary steps of polymerization, such as propagation, chain transfer to the monomer, and bimolecular chain termination. 相似文献
