The article discusses results of experimental research
of the influence of aprotic and proton solvents on reaction
rate of water molecules dissociation in the bipolar
membrane MB-1 by the method of electrochemical
impedance frequency spectrum. It was discovered, that
addition of organic component in aqueous solutions results
in significant influence on the parameters of water
dissociation in a bipolar region of the membrane.
The reason for this influence is the reduction of the
mass fraction of water in solution and, consequently,
in a bipolar region of the membrane, which itself reduces
the rate of the dissociation reaction. Another
reason for the influence of the organic solvent is its effect
on the network of hydrogen bonds existing in water
and aqueous solutions. Depending on the nature of
organic solvent and its concentration, the network of
hydrogen bonds may be strengthened, or destroyed,
thus facilitating removal of the proton involved in the
reactions between water molecules and catalytic centers
in cation-exchange and anion-exchange layer of
bipolar membrane, or retarding removal of proton.
This leads respectively to speed up or slow down the
rate of dissociation in the bipolar region of the membrane,
as well as changing the constants of the dissociation
reaction of water. Introduction of organic solvent
in solutions, which are in the contact with bipolar
membrane, is a convenient method of investigating the
role of solution composition on the rate of proton
transfer between water molecules and catalytic centers
in the membranes
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
The stability of strongly basic anion-exchange membranes MA-41-2P (JSC "Schekino-Nitrogen", Russia) and AMX (Tokuyama Soda, Japan) under intensive current regimes was investigated in the
current study. The process of water molecules dissociation at current densities above the limiting one in 0.01 M sodium chloride solution was studied in detail. The length of the electroconvective instability at the membrane / solution interface at currents
exceeding the limiting current was measured by laser interferometry
Data of the 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

In the article, we have investigated a number of characteristics of the sorption materials, the possibility of their use for the treatment of surface and waste water from oil and oil products. The rules of the cleaning oily water, the analytical solution for sorption purification process that takes into account the processes of filtration and sorption are listed. We have also estimated sorption capacity of sorbents and analyzed factors that influence it; the optimal conditions of the sorption process, depending on the conditions and the facilities for cleaning are sorted out. The possibility of purification of oil-contaminated water from heavy metal ions with the synthesized non-organic sorbent is shown
