Abstract

A study of the process of activation of molybdenumboride catalyst in the reaction of epoxidation of octene-1 with tert-butyl hydroperoxide and the effect on this process of the initial concentration of octene-1, tert-butyl hydroperoxide and the amount of catalyst in the reaction mixture. As well as reaction products (tert-butyl alcohol and epoxy). It is shown that over time a new amorphous phase is formed on the surface of Mo2B, which actually catalyzes the epoxidation reaction of octene-1 with tert-butyl hydroperoxide. The formation of this phase is the reason for the acceleration of the rate of consumption of hydroperoxide and the selectivity of the formation of epoxide over time.
