The kinetics of reactions between 4-nitrophenyloxirane and arenesulfonic acids YC6H4SO3H (Y = 4-OCH3, 4-CH3, H, 4-Cl, 3-NO2) in dioxane – diglime mixture (1:1, v:v) and in dioxane – dichloroethane mixture (7:3, v:v) at different temperatures have been studied. Cross-correlation analysis of multifactorial kinetic data was conducted. It was found, that combined effects of structures and temperatures in both reaction series are nonadditive. The isoparametric points with respect to the parameters of varied factors (structure and temperature) were evaluated and theirs mechanistic interpretation was proposed.
