Kinetics and mechanism of olefin epoxidation by hydroperoxide in the presence of molybdenum compounds

3. Kinetics of ethylbenzene hydroperoxide decomposition in the presence of molybdenum rezinate

Conclusions

  1. 1.

    Study has been made of the kinetics of the ethylbenzene hydroperoxide breakdown in the presence of molybdenum rezinate, working in ethylbenzene solution at temperatures ranging from 60 to 120°C.

  2. 2.

    Catalytic breakdown of ethylbenzene hydroperoxide proceeds through the formation of a complex between the hydroperoxide and the catalyst; it is inhibited by the product water and methylphenylcarbonyl in their competition with the hydroperoxide for positions within the catalyst coordination sphere.

  3. 3.

    The uncatalyzed reaction is first order in the hydroperoxide, the rate being 2–3 orders less than that of the catalyzed process.
