Mechanism of oxidation inhibition by metal complexes

1. Kinetics of oxidation of pentaerythrite esters of monocarboxylic acids by molecular oxygen

Conclusions

  1. 1.

    In oxidizing at 95–210°C, pentaerythrite esters of monocarboxylic acids follow a radical-chain mechanism with second-power chain breaking. Rate constants for chain extension and breaking have been determined; as have rate constants for hydroper oxide breakdown into free radicals. Effective rate constant for chain extension and breaking have been determined at 115°C.

  2. 2.

    A rate constant has been determined for cumene peroxide initiation at 110–140°C.
