Environmental problems of wood biomass processing. Waste processing lignin

in this paper the ecological problems of wood biomass processing are analyzed. The strongest attention is drawn to the problem of recycling and processing waste materials containing lignin with the help of high temperature self-propagating synthesis.     

Perspectives for thiamin as a preparation for correction of free radical states of different origin

Аntioxidant capacity of thiamin has been investigated, Liposome suspension being the standard biological test-system has been used for this purpose Antioxidant capacity of thiamin has been investigated. Liposome suspension being the standard biological test-system has been used for this purpose. Thiamin usually being not included in the list of antioxidant substances is able to interfere the processes of lipid peroxidation. Such effects give the possibility to extend the scale of thiamine practical application and to recommend it for correction different free radical states including environmentally induced free radical diseases.     

Amidation of Diamantane with Organic Nitriles and CBr<Subscript>4</Subscript> Under the Action of Granulated Zeolite FeHY

N-(1- and 4-diamantyl)amides have been synthesized by the reaction of diamantane with organic nitriles in the presence of CBr₄ under the action of granulated zeolite FeHY. The optimal ratios of the catalyst, reagents and the conditions for preparation of 1-N-diamantylamides in high yield have been found.     

Synthesis and Properties of Tetra(4-<Emphasis Type="Italic">tert</Emphasis>-butyl-5-phenylsulfanyl)phthalocyanines and Their Derivatives

The methods of synthesis of 4-tert-butyl-5-sulfanylphenyl-and 4-tert-butyl-5-(4'-carboxyphenylsulfanyl) phthalonitriles have been developed and on their basis the corresponding octa-substituted phthalocyanines have been prepared. The effect of the structure of the above phthalocyanine derivatives on their electronic absorption spectra and parameters of thermal degradation in the presence of air oxygen were studied.
