Hydrogen abstraction from (CH3),S and CH3COCH3 by CH3 radicals CH3+CH3SCH3 → CH4+CH3SCH2 CH3 + CH3COCH3 → CH4 + CH3COCH2 has been studied in the temperature range 120-245�. The rate constants, based on the value of 1013.34cm3 mol-l s-1 for the recombination of CH3 radicals, are given by (k in cm3 mol-1 s-1, E in kJ mol-1, R = 0.008314 kJ K-1 mol-1): logk1 = (11.62 � 0.08) ? (38.35 � 0.68)/2.303RT logk3 = (11.61 � 0.05) ? (40.48 � 0.46)/2.303RT Combination of the results for (1) with thermochemical data gives a calculated value of Logk-1 = (11.8 -63.7/2.303RT for the rate constant of the reverse reaction. The results for CH3+(CH3)2S are compared with all of the available data for hydrogen abstraction by free radicals from both sulphur-containing compounds, and molecules of the type (CH3)xM.
The article discusses the development of organomineral materials for the protection of metal parts of technological machines and structures operating mainly under the influence of an electrochemical environment. A technology has been developed for producing modified organomineral materials for anticorrosive coatings using micro- and nanosized particles of layered silicates (mineral fillers). The mechanism of the formation of nanocomposites using layered silicates and organic materials for anti-corrosion coatings formed by the activation-heliotechnological method is investigated. Using thermomechanical, physical and physico-chemical methods for studying the structure and properties of the materials obtained. Among these methods are: IR spectral analysis, scanning electron microscopy, thermogravimetry, as well as methods for determining the electrophysical and mechanical properties. And the improvement of the properties of organomineral protective coatings due to the formation of nanocomplex compounds in the interfacial layers of the binder-filler is proved
