ACTIVATION OF Mo2B CATALYST IN THE EPOXIDATION REACTION OF a-ETHYLALLYL ETHYL ACRYLATE WITH TERT-BUTYL HYDROPEROXIDE

The regularities of Mo2B catalyst activation in the epoxidation reaction of a-ethylallyl ethyl acrylate with tert-butyl hydroperoxide have been studied. It has been shown that the catalyst activation process is described by the Avrami-Erofeev topokinetic equation and includes two successive stages - the nucleation and formation of a new phase active in the epoxidation reaction. The formation of epoxy only occurs in the presence of the activated form of the catalyst. The effective and topochemical process constants have been calculated.
