研究了聚乳酸（PLA）的回收利用。以甲醇和碱金属卤化物为催化剂，降解聚乳酸生成乳酸甲酯，乳酸甲酯是一种适合聚乳酸再生的化学品。利用微波加热在不到20分钟内实现了优异的降解程度（转化率：> 99%，产率：>99%）。值得注意的是，PLA产品成功转化为乳酸甲酯。
The recycling of poly(lactide) (PLA) is studied. Using methanol and alkali-metal-halides as catalyst, PLA is degraded to produce methyl lactate, which is a suitable chemical for the regeneration of PLA. An excellent degree of degradation (conversions: >99%, yields: >99%) is achieved in less than 20 min utilizing microwave heating. Remarkably, PLA goods are successfully converted into methyl lactate.
