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 initial stages of liquid-phase oxidation of cyclooctene by molecular oxygen in the presence of tert-butyl hydroperoxide were investigated. It was shown that radical formation is the result of bimolecular decomposition of hydroperoxide. The influence of azodiizobutyronitrile on this process was studied. The kinetic parameters of the process were calculated.

The complex formation of molybdenum and vanadium borides in the reaction system of 1-octene epoxidation with tert-butyl hydroperoxide by infrared spectroscopic analysis was studied. It was shown that 1-octene formed complex with metal moiety in a case of molybdenum boride and with boron moiety in a case of vanadium boride.
