A THERMODYNAMIC STABILITY SCALE FOR STABLE, ISOLABLE FREE RADICALS.
Abstract
During the report period, seven galvinoxyl derivatives were placed on an approximate stability scale based on their affinities for the H atom furnished by diphenylpicrylhydrazine (in benzene). Although the stability scale is not very accurate, it appears to be essentially correct. The thermodynamic groundwork on which the scale is based allows the delta F values to be cross-checked. Four experiments on the galvinoxyl-diphenylpicrylhydrazine system were also performed in 90% tert. butyl alcohol-10% benzene. The value obtained for delta F is +0.97 = 0.02 kcal. at 30 degrees. Free radical scavenger experiments with Koelsch's radical are reported. (Author)
