| 摘 要： | 通过测定因载了不同量的氯化氢的聚（对氨基苯乙烯）和不同交换量的强酸性阳离子交换树脂催化的环己酮与乙二醇的缩酮化反应缩酮的收率，研究了聚合物固体酸催化剂的疏水性对其催化缩酮化反应性能的影响；发现在一定范围内增加催化剂的疏水性，可提高缩酮化反应的收率。

| Abstract: | The goal of this work was to reveal the influence of hydrophobicity of polymeric acid catalysts on their catalytic property for ketalization reaction.For this study,a series of poly( p -amino styrenes) with various amounts of supported hydrogen chloride,and a series of strongly acidic cation exchange resins with various exchange capacity were synthesized,and their catalytic property for ketalization of cyclohexanone and glycol were investigated.The results showed that the yields of ketal increased to somewhat with the increase of the hydrophobicity of the polymeric acid catalysts. |
