## Abstract The kinetics of the reaction of the superoxide ion with ethyl acetate have been studied in DMF, AN, and their mixtures. It was shown that the rate constants depend on the ethyl acetate concentration, which indicates the formation of an intermediate in this process. Equilibrium constants

The rate constants for the protonation of "free" (that is, solvated) superoxide ions by water and ethanol are equal to 0.5-3.5 X lO-~M-l.s-' in DMF and AN at 20'. It has been found that the protonation rates for the ion pairs of 0; with the BudN+ cation are much slower than those for "free" 0,. It i

## Abstract Absorption spectra of the superoxide ion have been studied in dimethylformamide (DMF) and acetonitrile (AN). It was found that the superoxide ion existed in equilibrium with an ion pair in AN (__K__~eq~ = 20__M__^βˆ’1^, Bu~4~N^+^ is the cation) and as β€œfree” (solvated) ion in DMF. The add
