Abstract:
The main volatile products of the pyrolysis of polyvinyl alcohol (PVA)-water, carbon oxides, acetaldehyde, methane, and hydrogen-were determined by gas chromatography with the use of a pyrolytic attachment to a chromatograph (so-called stepwise pyrolysis gas chromatography). The correlations of product ratios over various temperature ranges were found. It was demonstrated that the preliminary thermal oxidation of PVA in air at 200°C, which was responsible for the partial dehydration of PVA and the formation of thermally labile oxygen-containing groups in it, facilitated the occurrence of the subsequent carbonization phase. This manifested itself in much more intense dehydrogenation and methane release from the coke residue of thermally oxidized PVA in the region 700-900°C, when the elimination of oxygen-containing compounds was mainly complete, and in an increase in the yield of coke residue and the C: H ratio in this residue.
