摘要

以离子液体［Bmim］［Cl］为反应介质和催化剂，对废旧光盘的甲醇醇解反应进行了研究。考察了反应温度、反应时间、催化剂用量、甲醇用量对醇解反应结果的影响，得到的较佳醇解反应条件为反应温度110℃，反应时间1.5 h，n(甲醇)∶n(光盘)=8∶1，m(［Bmim］［Cl］)∶m(光盘)=1∶1，在上述条件下，光盘醇解率≥98%，双酚A收率≥93%。对离子液体的回用性能进行了考察，结果表明，离子液体回用8次后光盘的醇解率和BPA的收率无明显变化。采用FT-IR技术对醇解产物进行了表征。

Abstract

The methanolysis of waste compact discs (WCD) was studied using ionic liquid ［Bmim］［Cl］ as solvent and catalyst. The effects of reaction temperature

reaction time

ionic liquid dosage and methanol dosage on methanolysis results were examined. The obtained optimum reaction conditions were reaction temperature 110℃

reaction time 1.5 h

n(WCD)∶n(methanol)=1∶8

m(ionic liquids)∶m(WCD)=1∶1. Under above conditions

the conversion of WCD and yield of bisphenol A (BPA) were ≥98% and ≥93% respectively. The reusability of ionic liquid in the methanolysis was investigated

and the results showed that it could be reused up to 8 times without an apparent decrease in the conversion of WCD and yield of BPA under the given conditions. The structure of obtained product BPA was characterized by FT-IR.The methanolysis of waste compact discs (WCD) was studied using ionic liquid ［Bmim］［Cl］ as solvent and catalyst.
