Arbidol is proved to easily and completely react with electrogenerated bromine in the ratio 2: 9; so procedures for the arbidol
quantification in the neat substance and drugs are developed, the RSD value does not exceed 2%. A procedure for the coulometric
determination of water in the arbidol substance using the Fisher method is proposed. 相似文献

The dipole moment and Kerr effect methods showed that the dimer of benzoic acid has a conformation close to the twist form with a dihedral angle of 10°. The fraction of atomic polarization of the dimer is anomalously high (Pa 50% Pe), and it retains some polarity (DM 0.58 D).A. E.

It was found that nitroxoline rapidly and quantitatively reacts with electrogenerated chlorine or bromine. The stoichiometric coefficients of these reactions are 1: 1.5 and 1: 1, respectively. The mechanism of the reaction of nitroxoline with electrogenerated bromine was proposed. A procedure was developed for the quantitative determination of nitroxoline in the substance and pharmaceuticals with a relative standard deviation of 1–3%. 相似文献

Spatial structures of complexes [DyAc]2+, [DyBz]2+, [DyAc2]+ and [DyBz2]+ in aqueous solutions (Ac– and Bz–, acetate and benzoate anions, respectively) are studied using the paramagnetic double refraction method. The polyhedra of [DyAc(H2O)6]2+ and [DyBz(H2O)6]2+ are dodecahedra with ligands coordinated at one of the edges. In the complexes [DyAc2(H2O)4]+ and [DyBz2(H2O)4]+ the ligands are coordinated at the edges of a square antiprism at an angle of 50 (55)° to the local symmetry axis of higher symmetry.Translated fromIzvestiya Akademii Nauk.

The influence of the process conditions on the fatty acid composition and solid fat content of the products was examined for partial hydrogenation of sunflower oil in a static reactor using 1.0 wt% Pd/C powder catalyst. The solid fat content curves of the oil hydrogenation products were analyzed in relation to the process conditions. 相似文献

Heterogeneous equilibria in the manganese-carbamide-sulfuric acid-water quaternary system at 25°C are studied using the solubility method. The concentration boundaries are determined for crystallization of the initial solid components, eutectic compositions of the ternary systems, and binary compounds formed in the carbamide-sulfuric acid-water and carbamide-manganese sulfate-water systems, as well as for new compounds simultaneously containing carbamide, manganese sulfate, and sulfuric acid at a 1: 4: 1 and 1: 2: 1 ratios. 相似文献

A tuning method of a fiber Bragg grating by the bending compression-tension is considered. With this method, a relative tuning range of the resonance wavelength of the grating of about 5% has been obtained. The changes in the shape of the spectrum and in the grating reflectivity during the tuning process are studied. The reflectivity of the fiber Bragg grating has been found to considerably increase with increasing degree of compression. It is shown that such an increase is caused by compression-induced changes in the refractive index modulation amplitude in the grating. The fiber Bragg grating developed has been applied for tuning the radiation wavelength of an ytterbium fiber laser. The tuning range of the laser has been found to be 45 nm around the central wavelength 1080 nm. 相似文献

The Cotton-Mouton effect was used to investigate benzoic, phthalic, isophthalic, and terephthalic acids. The additive tensor characteristics of the magnetic susceptibility ellipsoid were obtained for the Car-COOH fragment. Magnetic and electric double refraction, dipole moment, and quantum chemistry methods were used to study the spatial structure of phthalic acid in solution.Translated fromIzvestiya Akademii Nauk.
