KINETICS OF EPOXIDE-CARBOXYLIC ACID REACTION

摘要

The kinetics of the addition reactions of four structural¬ly different epoxide compounds with glacial acetic acid in dioxane solution have been studied at 90*C, 110℃, and 125℃. The relative order of reactivity of the epoxides is styrene ox¬ide > vinyl cyclohexane monoxide > allyl 9, 10-epoxy stearate > l,2-epoxy-3-phenoxy propane. The reactions apparently follow the first-order-rate law with respect to epoxide and acid con¬centrations. For the four epoxides whose rates were determined, log10k was found to increase linearly with l/T according to the Arrhenius equation.
