Abstract
본 발명은 경질, 연질 폴리우레탄 발포 및 엘라스토머 등의 발포촉매로 사용되는 트리아민구조를 갖는 아래구조식(I)로 표시되는 3차아민의 제조방법에 관한 것으로,The present invention relates to a method for preparing a tertiary amine represented by the following structural formula (I) having a triamine structure used as a foaming catalyst such as hard, flexible polyurethane foam and elastomer,
위 식에서, n=1~5의 정수이다. 1차아민, 2차아민 혹은 고리구조를 갖는 아민화합물을 메틸화시켜 일반식 (I)의 3차아민 화합물을 제조함에 있어서, 상기 아민화합물을 포름산 및 파라포름알데히드와 반응시킨 후 가성소다 수용액으로 중화하여 염효과에 의해 층분리를 하여 제조한다.In the above formula, n = 1-5. In preparing a tertiary amine compound of general formula (I) by methylating a primary amine, a secondary amine or an amine compound having a ring structure, the amine compound is reacted with formic acid and paraformaldehyde and neutralized with an aqueous solution of caustic soda. To prepare a layer by the salt effect.
본 발명의 방법은 부반응이 거의 없고 정량적으로 반응이 진행되며 염효과에 의하여 펜타메틸디에틸렌트리아민이 물층과 분리되어 그 정제법이 간편한 새로운 제조방법이다.In the method of the present invention, there is almost no side reaction, the reaction proceeds quantitatively, and pentamethyldiethylenetriamine is separated from the water layer by the salt effect, and thus the purification method is simple.
