Conclusions

  1. 1.

    The rates of interaction of propylene oxide with formic acid were measured under conditions of liquid-phase oxidation of propylene in acetone solution, and the kinetic curves of the formation of propylene oxide in this process were constructed.

  2. 2.

    By comparing the kinetics of the formation of propylene oxide and the accumulation of the sum of the products (propylene oxide + propylene gycol + propylene glycol formate), it was established that a second pathway of consumption of propylene oxide with the formation of an unidentified (apparently high-boiling) product, appears under the influence of the formic acid formed.

  3. 3.

    The catalytic action of Teflon (the reactor material) is manifested in a decrease in the relative yield of the polymer product and in stoppage of the process of epoxidation of more profound stages than in the glass reactor.

  4. 4.

    The polymer product formed during oxidation lowers the reaction rate and reduces the maximum yield of propylene oxide, propylene gycol, and propylene glycol formate.
