Electrohydraulic effect in heterodisperse water-plant systems. II. Chemical nature of the suspended particles

On the basis of the results of acid hydrolysis, chromatographic analysis of the hydrolysates, and a study of IR spectra, it has been established that the suspended particles liberated under the action of electrohydraulic shocks on heterodisperse water—plant systems consist of small fragments of the lignocarbohydrate complex of the plant tissue.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent.

Development of quantum-chemical investigations of heterocycles at the Institute of Organic Chemistry,Russian Academy of Sciences (review)

Quantum-chemical investigations of the electronic structure and reactivity of five- and six-membered heteroaromatic compounds conducted at the N. D. Zelinsky Institute of Organic Chemistry, Russian Academy of Sciences, from the seventies of the twentieth century are reviewed and discussed.     

Investigation of the sorption of water vapor on cation-substituted vermiculite. 2. Thermodynamic description of sorption equilibria

The changes in the thermodynamic functions of the sorbents were calculated for the first time from measurements of the deformations of vermiculite during the sorption of water vapor and adsorption-calorimetric data.Institute of Physical Chemistry, Russian Academy of Sciences, 117915 Moscow.

Adsorption studies of organosubstituted laminar silicates. 1. Adsorption deformation of organosubstituted laminar silicates

A dilatometric method was used to determine the deformations of organosubstituted Pyzhevsk montmorillonite and synthetic fluorohectorite upon the adsorption of water, hexane, and benzene vapor. These results were compared with the adsorption calorimetry data. The dilatometric method was shown to be highly sensitive to structural changes of the laminar silicates.Institute of Physical Chemistry, Russian Academy of Sciences, 117915 Moscow.

Synthesis of 4-trifluoromethyl-7-hydroxycoumarin derivatives. Structure of 3-cyano-4-trifluoromethyl-7-acetoxycoumarin

A method was developed for the production of derivatives of 4-trifluoromethyl-7-hydroxycoumarin with electron-withdrawing groups (CN, CF₃CO) at position 3. The structure of 3-cyano-4-trifluoromethyl-7-acetoxycoumarin was proved by x-ray crystallographic investigation. The effect of the substituents on the geometry of the molecule is discussed.N. D.

Electrohydraulic effect in water-plant heterodisperse systems I. Compositions of the solid residue and the aqueous phase

The electrohydraulic (EH) treatment of water-plant heterodisperse systems leads to the partial degradation of the main components of the plant materials: lignin, cellulose, and carbohydrates. The presence of p-hydroxyphenyl and guaiacyl structures has been established on the basis of the results of the GLC analysis of the ether-extracted phenolic products of plant materials subjected to EH treatment. It has been shown that part of the carbohydrates passes into the aqueous phase in the form of free monosaccharides: pentoses and hexoses.Institute of Chemistry of Plant Substances of Uzbekistan Academy of Sciences, Tashkent.
