Epoxidation of ethylallyl ethylacrylate by tert-butyl hydroperoxide in thepresence of ammonium paramolybdate

The kinetics of epoxidation of ethylallyl ethylacrylate by tert-butyl hydro peroxide in the presence of (NH4)(6)Mo7O24 . 4H(2)O was studied. The orders of the reaction with respect to the hydroperoxide (n > 1), the catalyst (n < 1), and ethylallyl ethylacrylate (n = 0) were determined. The effects of the reaction products (2,3-epoxy-2-ethylpropyl ethylacrylate and tert-buta nol) and water on the reaction rate were examined. It was found that the ep oxide exerted no effect on the rate of this process; tert-butanol was an ac tivator: and water was an inhibitor of the reaction. The kinetic scheme of the process was considered. The overall rate law was obtained, and the kine tic parameters of the process were calculated; these parameters agree with the experimental values.
