Abstract

1. 청구범위에 기재된 발명이 속한 기술분야
본 발명은 3-메틸테트라히드로퓨란을 제조하는 신규방법에 관한 것이다.
2. 발명이 해결하려고 하는 기술적 과제
종래의 3-메틸테트라히드로퓨란의 다양한 제조법에서는 출발물질의 확보가 어렵고, 수소화 조건이 가혹하며, 부산물이 생성되어 이것을 분리할 때 많은 에너지가 필요할 뿐 아니라, 생성물의 수율이 낮아 공업적으로 실시하기에는 곤란하여, 이러한 문제점을 해소하고, 또한 공업적으로 유용한 방법으로 3-메틸테트라히드로퓨란을 제조하는 방법을 제공한다.
3. 발명의 해결방법의 요지
본 발명은 메타크릴산에스테르를 일산화탄소 및 저급지방족알코올과 반응시켜 메틸숙신산디에스테르를 얻고, 이어서 이것을 수소화 및 탈수고리화 하여 이루어진 3-메틸테트라히드로퓨란의 제조방법이다.
4. 발명의 중요한 용도
이 방법에 의하면, 값싼 출발물질로부터 3-메틸테트라히드로퓨란을 효율적으로 얻는 것이 가능하다.
