Abstract
The effect of the viscosity of a toluene solution, with addition of Va seline 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 viscosit y's activation energy in these systems. The effects studied were attri buted to van der Waals solvation of partners by long molecules of the Vaseline oil alkanes.
