We have studied molecular weight parameters of the products prepared via chemical modification of cellulose nitrates with aliphatic alcohols. Proceeding from the quantum-chemical simulation data the most probable pathways of degradation of cellulose nitrate macromolecules have been elucidated.

The possibility of using waste processing of cereal crops for the removal of copper ions from model solutions. Sorption characteristics determined amniotic membrane wheat, oats and barley relative to copper ions. It is shown that treatment of fruit shells solutions of sulfuric acid concentration increases the low adsorption capacity. Found that the sorption materials of the most studied sorption capacity with respect to the copper ions have a fruit shell wheat

Effect of salt of bis(hydroxy metil)phosphinic acid on biocenose of yeast culture used in the generation of ethanol from sugar was investigated. It was found that the amount of released carbon dioxide in the experiment with the addition of salt about 3 4 times exceeded the experiment comparing. Analysis of distilled ethanol by chromatography-mass spectroscopy revealed that investigated the salt only affects the output on co-products in bioprocess synthesis of ethanol. Qualitative and quantitative composition of distilled ethanol were determined.

Reactions of high nitrogen-containing cellulose nitrate with a series of aliphatic alcohols are studied. In the course of physicochemical studies most probable pathways of chemical reaction were established. They include substitution of nitrate groups by alkoxy group, opening of glucopyranose ring with the addition of the fragment of alcohol by the free bonds formed and formation of the carbonyl group, and also saponification of nitrate groups while studying the process in alkaline medium.

The interaction of cellulose nitrate with asymmetrical dimethylhydrazine and carboxylic acid hydrazides was studied. The most probable pathways of reactions were established on the base of physical-chemical studies.
