摘要
采用几种不同离子液体作为催化剂,采用微波辅助醇解法,研究废弃聚酯PET在不同多元醇(乙二醇,丙三醇,1,4-丁二醇)中的醇解机理并利用红外光谱初步判定醇解产物结构,综合三种表征,最终得到不同多元醇醇解PET的醇解机理.与此同时微波反应大大缩短了解聚时间,提高了解聚反应的效率.
Using several different ionic liquids as catalyst, the waste PET alcoholysis mechanism in different polyhydric Alcohol is studied by the microwave alcoholysis product is determined by IR spectrum. The d is gained. At the same time, by the microwave reaction, the efficiency of the polymerization. -assisted alcoholysis method, and the structure of egradation mecharism of PET the time to understand gather in polyhydric alcohol is shorten to improve
