| 摘 要： | 以全氟壬烯为氟溶剂, 对物质的量的羧酸和醇的酯化反应进行了系统研究. 在不移走生成物的条件下, 酯与全氟壬烯能形成氟两相体系而脱离酯化可逆反应体系, 促进反应平衡右移, 使收率提高10%～47%, 氟溶剂通过冷却和简单的相分离, 就可回收并直接套用. 氟溶剂在有机相中的损失小. 在氟溶剂中的酯化反应回流温度有较大幅度的下降.

| Abstract: | Esterification of various acids with various alcohols at equivalent molar ratio of acid to alcohol has been investigated,using perfluorous nonene as a fluorous solvent. This novel approach provided an in-creased the product yields by a magnitude of 10% to 47%. The use of perfluorous nonene solvent allowed the formation of a fluorous biphase system with the ester products thereby driving the esterification equilib-rium to move rightly. The fluorous solvent could be recovered and reused by simple phase separation with little loss. In the esterification with fluorous solvent,the reflux temperatures were much lower. |
