ESR ANALYSIS OF PROTON TRANSFER IN VISCOUS MEDIA

Article abstract of DOI:10.1007/BF00863573

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.
