Abstract
Treatment of polyamides in an ionic liquid at 300 degrees C resulted in the efficient depolymerization of polyamides to give corresponding monomeric lactam in good yields. The recovered monomer was collected by direct distillation of the reaction mixture. PP13 TFSI furnished the best results for the depolymerization. The ionic liquid could be recycled five times in the present reaction.
摘要
在300摄氏度的离子液体中处理聚酰胺，可使聚酰胺高效解聚，以良好的产率得到相应的单体内酰胺。通过直接蒸馏反应混合物来收集回收的单体。PP13 TFSI在解聚反应中效果最佳。在本反应中，离子液体可循环使用五次。
