R 45 Resistance of polyfluorinated complete esters of polyhydric alcohols to thermal oxidation: Comparison with nonfluorinated analogs [Electronic resource] / T. I. Gorbunova, S. M. Sorokina, A. Ya. Zapevalov, V. I. Saloutin // Russian Journal of General Chemistry. - 2006. - Vol. 76, № 11. - P1795-1800 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Complete esters of pentaerythritol, trimethylolpropane, and 2,2-dimethyl-1,3-propanediol with polyfluorinated carboxylic acids were prepared by esterification. As determined by differential thermal gravimetric analysis in air, the resistance of the esters to thermal oxidation decreases in going from pentaerythritol derivatives to those of trimethylolpropane and then to those of 2,2-dimethyl-1,3-propanediol. The compounds synthesized surpass their nonfluorinated analogs in the resistance to thermal oxidation. \\\\Expert2\\nbo\\Russian Journal of General Chemistry\\2006, V. 76, N 11, p.1795.pdf |
