摘要/Abstract

摘要：

以离子液体[Bmim][OAc]为反应介质和催化剂, 对聚乳酸 (PLA)丁醇醇解反应进行了研究。考察了反应温度、反应时间、离子液体用量、丁醇(n-butanol)用量对反应结果的影响。得到较佳工艺条件为:反应温度为150℃、反应时间为3 h、m([Bmim][OAc]):m(PLA)=0.2:1、n(n-butanol):n(PLA)=5:1。在上述条件下, PLA醇解反应转化率≥81%, 乳酸正丁酯收率≥70%。采用FT-IR技术对产品的结构进行了表征。离子液体的回用性能结果表明:[Bmim][OAc]重复利用6次后, PLA转化率和乳酸正丁酯收率无明显变化。

Abstract:

The butanolysis of poly(lactic acid) (PLA) was studied using ionic liquid [Bmim][OAc] as solvent and catalyst. The effects of reaction temperature, reaction time, ionic liquid dosage and n-butanol dosage were examined. It was indicated that the conversion of PLA was≥81% and the yield of n-butyl lactate was≥70% under the following conditions: reaction temperature 150℃, reaction time 3 h, m([Bmim][OAc]):m(PLA)=0.2:1 and n(n-butanol):n(PLA)=5:1. Reusability of ionic liquid showed that [Bmim][OAc] could be reused up to 6 times without change in the conversion of PLA and yield of n-butyl lactate.

Key words: ionic liquid, poly(lactic acid), butanolysis, n-butyl lactate
