Combined wet oxidation and alkaline hydrolysis of polyvinylchloride
In view of the widespread aversion to burning polyvinylchloride (PVC) together with municipal waste, we have attempted an alternative approach to its decomposition. This paper describes a combined wet oxidation/alkaline hydrolysis yielding water soluble, biodegradable products. Experiments were carried out at temperatures from 180-260 degree C and reaction times of 8-24 min.
The chloride liberated provides information on the rate constants. Considering the measured Cl- and Chemical Oxygen Demand (COD) values, we find hydrolysis and oxidation processes to be interdependent. The main products are Cl- and CO-2, the rest comprising a range of water-soluble compounds, a small, Cl-free residue, and a recognizable amount of H-2.
