摘要：The PVC pressurized hydrolysis dechlorination has been studied in an autoclave reactor under different operating conditions such as temperature, reaction time, and alkali concentration. About 95% of the chlorine in PVC can be effectively removed within 2 h at temperature 240 degreesC in hydrolysis process. The HCl yield increases and residue yield decreases with the increasing of hydrolysis temperature. The structure of residue was analyzed by using FTIR and SEM. It was found that the hydrolysis dechlorination process has advantages over the thermal decomposition of PVC.
