Claims (6)
- 히드록시아민 술페이트와 하기 일반식(II)의 알데히드를 반응시키고 후속적으로 탈수시켜 하기 일반식(I)의 니트릴을 제조하는 방법에 있어서, 반응이 프로피온산 나트륨 존재하의 프로피온산중에서 대기압하에 외부 온도 140 내지 165℃에서 2시간 내지 6시간 동안 가열함과 동시에 용액이 형성될때 까지 이 계로부터 프로피온산 및 물의 혼합물을 증류시킴으로써 수행되고, 100 내지 130℃에서 진공 증류에 의해 프로피온산 및 물의 혼합물을 제거한 다음, 제조된 니트릴을 일반적인 방법에 의해 분리해내는 것을 포함하며, 상기 방법에서 히드록시아민 술페이트는 알데히드 1몰을 기준하여 0.505 내지 0.58몰의 양으로 부가되고, 또 프로피온산 나트륨은 히드록시아민 술페이트 1몰을 기준하여 1.05 내지 1.3몰의 양으로 부가되는 것을 특징으로 하는 하기 일반식(I)의 니트릴을 제조하는 방법:상기식에서, R은 수소, C1-C4알킬 또는 페닐이다.
- 제1항에 있어서, R이 4-위치에 있는 방법.
- 제2항에 있어서, R이 3차부틸 또는 페닐인 방법.
- 제2항에 있어서, R이 페닐인 방법.
- 제1항에 있어서, 프로피온산을 알데히드 1몰 기준으로 10 내지 20몰의 양으로 부가하는 방법.
- 제1항에 있어서, 반응이 150 내지 160℃에서 3시간 내지 5시간 동안 가열함으로써 수행되고 이 프로피온산 및 물의 혼합물이 110 내지 120℃에서 진공 증류에 의해 제거되는 것을 특징으로 하는 방법.
