Claims (2)
- (메트)아크릴산을 산성 촉매의 존재하에 1,4-부탄디올과 반응시켜 4-하이드록시부틸 (메트)아크릴레이트를 제조하는 방법에 있어서, 1,4-부탄디올 디(메트)아크릴레이트를 반응 초기에 첨가함으로써 반응계에서 다음 식(1)의 관계가 유지되도록 하고, 또한, 첨가한 (메트)아크릴산에 대한 첨가한 1,4-부탄디올 디(메트)아크릴레이트의 몰 비가 다음 식(2)의 범위에 있고, 단 식(1)의 계산에 있어서, 반응 초기에 첨가됨으로써, 또는 반응하는 동안에 형성됨으로써 반응계에 존재하는 1,4-부탄디올 디(메트)아크릴레이트와 4-하이드록시부틸 (메트)아크릴레이트는 둘다 1,4-부탄디올 디(메트)아크릴레이트 1몰당 1,4-부탄디올 1몰과 (메트)아크릴산 2몰의 존재에 상응하는 1,4-부탄디올 디(메트)아크리레이트와 4-하이드록시부틸 (메트)아크릴레이트 1몰당 1,4-부탄디올 1몰과 (메트)아크릴산 1몰의 존재에 상응하는 4-하이드록시부틸 (메트)아크릴레이트를 취함으로써 계산에 포함됨을 특징으로 하는 방법.
- 제1항에 있어서, 반응 완료 후, 1,4-부탄디올 디(메트)아크릴레이트를 펜탄, 헥산, 헵탄 및 옥탄으로 이루어진 그룹으로부터 선택된 하나 이상의 추출 용매를 사용하여 반응용액으로부터 추출하여 1,4-부탄디올 디(메트)아크릴레이트를 함유하는 추출물을 수득하며, 추출 후에 잔류 용액으로부터 4-하이드록시부틸 (메트)아크릴레이트를 회수하고, 1,4-부탄디올 디(메트)아크릴레이트를 함유하는 추출물을 그 자체로 또는 이로부터 추출 용매를 제거한 후에 반응계로 반송하는 방법.
