Dehydrochlorination kinetics of polyvinylchloride (PVC) solutions in dimethylformamide

Optimizing hydrothermal dechlorination of PVC in a SS-316 reactor: From chemistry knowledge to material considerations

“…In the case of the HCl evolution route, some authors claimed that the in-situ generated HCl acts as a self-catalyzer for PVC dechlorination. In contrast, others believed that the generation of HCl restricts the activation of catalysts and plays an important role in inhibiting the dechlorination rate [22,54]. The observed inactivity of the K 2 CO 3 and TiO 2 catalysts in accelerating the Cl removal rate may be due to such pH damping impact by these materials.…”
