N2 - Oxidative degradation of rigid-PVC pellets (R-PVC) with oxygen was carried out in 1-25 mol/kg-H2O (m) NaOH solutions, at 150-260 °C and Po2 of 1-10 MPa in order to investigate the chemical recycling of PVC materials. The apparent rate of oxidative degradation of R-PVC progressed as a zero order reaction, and the apparent activation energy was 38.5 kJ mol-1. The major products were oxalic acid, a mixture of benzenecarboxylic acids, and CO2. The tin in R-PVC was extracted completely. This paper reports the possibility of converting PVC materials into raw materials such as carboxylic acids by chemical recycling.
