水热降解聚氯乙烯废弃物的研究

Hydrthermal degradation of polyvinyl chloride

以超临界水为反应媒介,氢氧化钙为脱氯剂,将聚氯乙烯(PVC)废弃物转化为粒径在100～200nm的碳纳米颗粒。利用粉末X射线衍射、透射电子显微镜和拉曼光谱等手段对碳纳米颗粒进行了表征。并对该水热降解反应的机理进行了探讨。

Polyvinyl chloridesimple （PVC） has been transformed into carbon nanoparticles with diameter of 100 -200 nm in supercritical water using Ca （OH）2 as dechlorine reagent. The products have been characterized by X - ray diffraction, transmission electron microscopy and micro - Raman spectroscopy. The probable mechanism of this hydrothermal reaction is tentatively discussed.
