摘　　要：研究了废旧聚酯PET以微波辐射为能量源在1,4-丁二醇、丙三醇、乙二醇和1,2-丙二醇等几种多元醇中的醇解反应.研究结果表明除1,2-丙二醇,PET在其他三种多元醇中均能得到很好的醇解转化率.根据对醇解产物和醇解过程的分析,给出了可能的醇解机理.The alcoholysis reactions of waste PET in various polyalcohol, such as 1,4 - butanediol, glycerol, glycol, and 1,2 -propanediol, are studied under microwave radiation. The research results indicate that favorable conversion of PET are achieved in all the three kinds of polyalcohol only except the 1, 2- propanediol. The mechanism of the glycolysis has been proposed based on the analysis of alcoholysis products and processes.
