使用可重复使用的催化剂三氟甲磺酸钪[Sc(OTF) 3]和三氟甲磺酰亚胺钪[Sc(NTF 2) 3]在室温下缩聚一步合成脂肪族聚酯。可重复使用的催化剂在室温下催化羧酸和醇的直接酯化反应。采用Sc(OTF) 3 在35℃减压下进行甲基琥珀酸与二醇的缩聚反应。结果表明，Sc(OTF) 3 具有较高的活性、耐水性和周转数(TON)，可以有效地催化直接缩聚反应。
The one-step synthesis of aliphatic polyesters at room temperature polycondensation was carried out using reusable catalysts, scandium trifluoromethanesulfonate [Sc (OTF) 3] and scandium trifluromethanesulfonimide [Sc (NTF 2) 3]. The reusable catalysts catalyzed the direct esterification of carboxylic acid and alcohols at room temperature. The polycondensations of methylsuccinic acid and diols were carried out under reduced pressure using Sc (OTF) 3 at 35 C. The results show that the Sc (OTF) 3 catalyzed the direct polycondensation effectively because of high activity, resistance to water and turnover number (TON).
