Quantum solitons are discovered with the help of generalized quantum hydrodynamics. The solitons have the character of the stable quantum objects in the self consistent electric field. The theory of quantum solitons lead to explanation of the existence of stable atom structures on the microscopic level and lightning balls on the macroscopic level of description of physical systems. The delivered theory demonstrates the great possibilities of the generalized quantum hydrodynamics in investigation of the quantum solitons. The paper can be considered also as comments and prolongation of the materials published in the known author`s monograph (Boris V. Alexeev, Generalized Boltzmann Physical Kinetics. Elsevier. 2004). The theory leads to solitons as typical formations in the generalized quantum hydrodynamics.

A polynomial method of Cauchy problem solving is presented. The method allows constructing a fundamental solution in locally analytical form for any type of function of the right part of the equation for normal form of differential equation. A test for well-known functions both for lower and higher among possible orders of polynomial method of solving is carried out. The expediency of using the method of higher order is determined.

On the basis of entropy production criteria components of an estimation of an rectification columns power supply optimum level are developed for a case binary and multicomponent mixtures of any physical and chemical nature. By means of these criteria the levels of optimal power supply confirmed with data of natural experiment are defined.

The results of the study on reactions of reetherification and acylation of 3-aminopropyltryethoxysilan and 2-(aminoethyl)-3-(trymethoxysilyl)propylamine are presented. The possibility of preparation of the line and geterocycle organosilicon compounds containing nitrogen is shown. The schemes of processes that pass on the initial steps of preparation of polymerizing adgesives are proposed.

The submitted work observes the ultrasonic low-frequency (30 кHz) extraction and investigates the basic physicochemical properties of flax seeds polysaccharide extracts. The developed technique allows to decrease extraction time (from 24 hrs to 16 min) under retention of structure of polysaccharides.

The stripping voltammetry with the exchange of the solution without of the opening of the electrochemical circuit was applied to study the effect of the composition of the aqueous solutions, containing aliphatic alcohols on the height and potential of the peak current for Pb (II) and Cd (II). The effect of ethyl, n-propyl, n-butyl, and n-amyl alcohols was studied. The interference of the alcohols is increased with the increasing of the length of the hydrocarbon chain within the alcohol, which probably is caused by the adsorption of the alcohol onto the electrode surface.

The stripping voltammetry on the mercury film electrode with the change of the solution without of the opening of the electrochemical circuit was applied to characterize the behavior of Pb (II) and Cd (II) in aqueous solutions, containing Triton X-100 and aliphatic alcohols, namely ethyl, n-propyl, n-butyl, and n-amyl alcohol. The effect of the length of the hydrocarbon chain in the alcohol on the peak current of Pb (II) and Cd (II) was studied. The presence of Triton X-100 eliminates the interference of alcohols while stripping analysis of Pb (II) and Cd (II) due to the formation of mixed micelles

The properties of butadiene-styrene latexes, stabylized by the mixes of surface-active substances included silicon SAS, practically unsolved in water, were investigated. It was shown that they are characterized by low foaming, practically unswollen in water and stable in the solutions of electrolites

The thermodynamic model of the nanoadhesion effect in polymer particulate-filled nanocomposites was considered, which was demonstrated a good correspondence to experimental data. It was shown that the nanoadhesion effect has dimensional origin, i.e. it is true nanoeffect. A nanofiller particles aggregation influences strongly on indicated effect.

Effect of molecular mass (MM) and molecular-mass distribution (MMD) on surface tension of oligomers has been investigated. Narrow fraction of polyethyleneglycols (from 300 to 40000) and their double and triple mixtures of different composition was used as model. Obtained results prove possibility of regulation surface tension of oligomers and polymers by changing MM and MMD and indicated that stability system’s behaviour increases with enlargement of MMD of oligomer mixtures.

Introduction in structure of drugs carbohydrate components lead to increasing solubility in water, detoxication and prolongation of biological action in organism. Method of synthesis polymeric forms of isoniazid include reaction oligochitosan, N-hydroxymethylchitosan and N-chloro-2- hydroxypropylchitozan with antiphthisic substance. Hydrophilic polymeric base of streptomycin sulfate was prepared by reactions chitosan with antibiotics sulfate. Synthesized water-soluble analogues of 1,4-β-2-amino-2-desoxy-D-glucan with side chains containing amino acids with the formation of covalent linkage through methylene or hydroxypropylene spacer. As a polymer matrix for the immobilization of glycine, L-lysine and its hydrochloride, L-glutamic acid used chitosan, Nhydroxymethylchitosan, N-chloro-2-hydroxypropylchitosan and 3-hydroxymethyl-3-deoxy-starch.

The methodology of designing of water resource-saving chemical process of glass works has been proposed. The basis of it is thermodynamic approach to analysis and synthesis (designing) of processes (the application of thermodynamic exergy method). The proposed methodology was approved by water chemical process designing of large-scale glass enterprises (production of glass fiber, glass cloth, hardened glass).
