| Abstract: | The properties of the ion associates of benzophenone (BP) free radicals with Na+ and Li+ have been investigated polarographically in dimethylformamide. It was found that BP? forms ion pairs with Na+ (Kass=69 M?1) and two types of associates with Li+: BP?...Li+ (Kass,1=330 M?1) and BP?...(Li+)2(Kass,2M?2). The influence of temperature on the equilibria was also discussed. The ion associates with Li+ disappear in a disproportionation reaction; the mechanism and kinetics of that reaction were studied. It was found that the main contribution to the overall kinetics are made by the pairs (a) BP?...Li++BP?...Li+, (b) BP?+BP?...(Li+)2 (c) BP?...Li++BP?...(Li+)2. |
