| 摘 要： | 将具有不同ＰＥＧ含量的交联聚苯乙烯固载聚乙二醇树脂用于催化环已稀的二氯卡宾加成和乙酰苯胺的Ｎ－丁基化反应，发现树脂ＰＥＧ含量与催化剂活性之间存在的依赖关系。通过测定不同ＰＥＧ含量的树脂分别在水和甲苯中的溶胀系数，用树脂亲油－亲水性的变化规律，解释树脂活性与ＰＥＧ含量之间的依赖关系。

| Abstract: | Polystyrene supporteo polyethylene glycol resin(PS-PEG-400 )with various PEG conten t was used as immobilized phase transfer catalyst for reactions of the addition of cyclohexenewith dichlorocarbene and N-butylation of acetanilide. The depondence of catalytic activity ofthe resin on PEG content was explained by the lipophilicity and hydrophilicity. |
