Activation of Mo2B Catalyst in the Epoxidation Reaction of α-Ethylallyl Ethyl Acrylate with tert-Butyl Hydroperoxide
The regularities of Mo2B catalyst activation in the epoxidation reaction of $\alpha$-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 forma- tion of epoxy only occurs in the presence of the activated form of the catalyst. The effective and topochemical process constants have been calculated.
