Résumé : The kinetic study of the alcaline hydrolysis of methyl acrylate and propiolate, in acetone 70% — water 30%, have been made. The rate of hydrolysis of methyl propiolate is to fast to be measured: at‐12° the reaction is finished in less than 4 minutes. In the case of methyl acrylate the Arrhenius parameters are: E=12,9 Kcal./mole log PZ=8,27. Copyright © 1955 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim
