摘　　要：用邻氯苯乙烯、间氯苯乙烯、对氯苯乙烯与二乙烯基苯合成3种氯代苯乙烯强酸性阳离子交换树脂,考察它们的热稳定性,结果表明:以邻氯苯乙烯强酸性阳离子交换树脂的热稳定性能最好,在170℃的水介质中,磺酸基100 h热降解率小于14.0%,降解速率为0.002 8%/h。用作二壬基酚和苯酚烷基化转移反应的催化剂,二壬基酚的转化率达99%以上,树脂在反应体系中稳定。Three chlorostyrene strongly acidic cation exchange resins were prepared from o-, m-, p-chorostyrene and divinylbenzene. The thermal stability of o-chlorostyrene strongly acidic cation exchange resin was the highest. In water at 170℃ the degradation of the prepared resin was less than 14.0% in 100 hours, and degradation rate was 0.0028%/11. In the transalkylation of dinonanylphenol with phenol by using the prepared resin as catalyst, the conversion of dinonanylphenol was more than 99%, and the resin had good stability in this reaction system.
