Kinetics of Reaction in Ethanol Solution from −80° C. to +20° C.

Abstract

RATES of reaction in solution have not usually been measured over a range of temperature greater than about 50° C. Measurements over a bigger range would give more accurate values of the energy and entropy of activation, and interesting deviations from the linear Arrhenius relation between log k and 1/T might be expected, especially in proton-transfer reactions1. We have measured the rate between −80° C. and + 20° C. of the reaction between ethoxide ion and trinitrotoluene in ethanol, which appears to proceed by a proton transfer:
