The interaction of 3,6-di-tert-butyl-2-hydroxyphenoxyl with triethylamine in the reaction of proton transfer is catalyzed by water.However, the rate of proton exchange with diethylamine is independent of water admixtures in the reaction medium.ESR showed that the complexing of 3,6-di-tert-butyl-2-hydroxyphenoxyl with water leads to redistribution of the spin density. - Key words: 3,6-di-tert-butyl-2-hydroxyphenoxyl; triethylamine; diethylamine; complexing; ESR.

The effect of the viscosity of a toluene solution, with addition of Vaseline oil, on the kinetics of proton transfer from 3,6-di-tert-butyl-2-hydroxyphenoxyl to triethylamine was analyzed by the ESR technique.Activation barriers of the reaction do not correlate with the viscosity's activation energy in these systems.The effects studied were attributed to van der Waals solvation of partners by long molecules of the Vaseline oil alkanes. Keywords: proton transfer, 3,6-di-tert-butyl-2-hydroxyphenoxyl, activation parameters, ion pairs, viscosity.
