In the article the mathematical model of the space charge region in the bipolar membrane is considered. The structure of the space charge region under passing of electric current, and without electric current is discussed. The results of experimental studies of water dissociation in the bipolar membrane in the presence of chromium(III) are discussed
The article shows the information of the use of 2-R-sulfanyl nicotinates of potassium on rice crops. We have found that the compounds described increase yield and improve its quality
Correlations between experimental dipoles moments and values of the difference of first potentials ionization of atoms and molecules (ΔE) for three -coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I ) are described.
Exponential functions of dependence μ= f(ΔE) for rows ЭF3 andЭCl3 are received. Within the valence of shell electron pair repulsion theory it is shown, that the molecular dipole moments can be divided to dipol moments of ions of separate atoms, which, naturally changing, are transferred in the ranks of molecules ЭХ3
New 2-R-4-hydroxymethyl-6-methylnikotinates of alkaline metals are synthesized by alkaline hydrolysis of derivatives 6-methyl-1,3-dihydrofuro-[3,4-c]pyridine-3-on
In the article we have optimized reaction conditions of furfurilidenatseton with epichlorohydrin in the presence of a catalyst of tin chloride and held hydrogenation of double bond of 2-methylene -2 - [(2-furyl]-X-1,3 – dioxolan; we have also given the
biological activity of some unsaturated furan 1,3- dioxolans
Data of application of researches of vegetative components in reception of drinks from dairy whey of a functional purpose are shown
Correlations between values of the differences of first
potentials ionization of atoms and molecules (ΔE) and
valency angels α for three coordinated molecules of
types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl,
Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te;
X = CH3, SiH3, GeH3) are described in this article.
It is shown, that the entered value ΔE can serve as
additive measure of change of the valency angle α in
the basic and raised stances. We have also established
that the functional dependences correlate with changes
in the of hybridization of orbitals and the R
parameters characterizing the interaction of electronic
pairs near the central Э atom
The method of nanoemulsions obtaining with acoustic chemistry method has been considered in the article, the nanoemulsion formula has been found. The researches for emulsion stability and particle sizes determination have been fulfilled. The antioxidant effect of the obtained emulsion and a possibility to use it in meat-vegetable products have been researched
3-Pyrrol-1-ylthieno[3,2-b]pyridin-2-carboxylic acid[(phenyl, 1,3-benzodioxol-5-yl)methylen]-hydrazides were synthesized by the reaction of
3-pirrol-1-ilthieno[2,3-b]pyridine-2-carbohydra-zides with aromatic aldehydes
The present review highlights the theoretical founda-tions of electric activation of aqueous solutions, their characteristics and properties
