The rate oxidation reaction of quinoline with peroxy acid in warious organic solvents was studded. It has been found effective rate constants (k) and activation energy (Ea) studded process. Between the parameters of the transition state ΔН≠ and ΔЅ≠ is a linear relationship, indication the presence of counteraction effect in our series of experiments. The rate of oxidation and activation energy inflation of solvation peroxyacids and quinoline. The reaction medium affects the rate of oxidation. Correlation equations between the rate constants of the reactions in study and the physicochemical parameters of the solvents were proposed. The correlation equation for effective rate constants and the basic physicochemical parameters of solvents at 303 K has the form lg k = 0.2103 + (11.2719 ±1.7750)f(n) + (1.2126 ± 0.3906)f (ε) + +(0.0002 ± 0.0008)B – (0.0209 ± 0.0079)ET – (0.0019 ± 0.0007)δ2 – – (0.0130 ± 0.0018)Vм ( 1) N = 9; R = 0,9899; S = 0.0591; F = 119.4348, N = 9; R = 0,9737; S = ±0.0950; F = 30.3963. Correlation equations for effective rate constants for other temperatures are similar. The correlation equation for effective energies (Ea) of activation and the basic physicochemical parameters of solvents has the form lg Eак = 4.8998 – (18.7772 ± 0.4915) f(n) + (1.8883 ± 0.1038) f(ε) – – (0.0077 ± 0.0002)B – (0.0304 ± 0.0014)Eт + (0.0050 ± 0.0001) δ2 + + (0.0108 ± 0.0005)Vм (2) N = 8; R = 0.9982; S = ±0.0103; F = 1513.94. The proposed correlation equations relate the parameters of the transition state of the oxidation process and the physic-chemical parameters of solvents.
