: the process of removing hydrogen and chlorine or hydrogen chloride from a compound.

What is dehydrochlorination of PVC?

Dehydrochlorination of PVC Materials in Hydrogen and Nitrogen. ... An amount of 90% of HCl has been removed from PVC up to 250 °C. After that it increases slowly, and the release of chlorine as HCl of PVC has reached 95% at about 300 °C. No change has been found after 300 °C.

Which is used to reduce evaluation of HCl in PVC?

In the early works on PVC dehydrochlorination, Arlman¹⁰¹ ruled out the possibility of an autocatalytic effect of HCl on PVC degradation kinetics. ... In water, HCl was quickly dissolving and therefore it was removed faster from contact with PVC. Figure 4.7 shows that dehydrochlorination in water occurs with a reduced rate.
