Abstract: 본 기술은 용매를 이용한 락타이드 제조방법으로서, 락타이드를 제조할 때 두번째 단계에서 이온성 액체를 용매로 사용하여 반응물의 모빌러티를 확보하여 반응 온도를 낮추고 반응 중 발생하는 수분을 이온성 액체에서 흡수하여 수분에 취약한 락타이드가 분해가 일어나지 않도록 할 수 있다. 뿐만 아니라 지속적인 올리고머 투입에 의한 연속적인 락타이드 제조가 가능하게 된다. 이온성 액체에 의해 반응 부산물에 의한 반응기 오염이 최소화되어 반응기 세척을 위한 용매가 불필요하게 된다. 더불어 이온성 액체의 높은 끓는점으로 인해 이온성 액체의 회수 및 재활용도 용이한 장점이 있다.
