Thorough dechlorination of poly (vinyl chloride) and applications of the dechlorinated solid

聚氯乙烯(PVC)在氧化锌存在下完全脱氯，在较低温度下不放出HCl气体。对脱氯后的聚氯乙烯进行磺化反应，生成吸附剂和催化剂。磺化固体的阳离子交换容量约为2meq/g，接近商业阳离子交换树脂的值。磺化样品从气相中吸附有机化合物，特别是芳香族化合物，并激活了气相乙醇脱水反应。

Poly (vinyl chloride) (PVC) was thoroughly dechlorinated in the presence of zinc(II) oxide without evolving HCl gas at a lower temperature. Sulfonation of the dechlorinated PVC was conduced to induce adsorbents and catalysts. Cation exchange capacity of the sulfonated solid was ca.2meq/g close to the value of a commercially available cation exchange resin. The sulfonated sample adsorbed organic compounds from vapor phase, especially an aromatic compound, and activated a vapor phase alcohol dehydration reaction.
