Claims (3)
유기용매중에서 다음식(Ⅰ)의 과산화물의 존재하에 탄산암모늄과 다음식(Ⅱ)의 케톤을 반응시켜 다음식(Ⅲ)의 케타진을 얻고, 그다음 케타진을 분리하여 산가수분해시킴을 특징으로 하는 히드라진의 제조방법 :In an organic solvent, ammonium carbonate was reacted with a ketone of formula (II) in the presence of a peroxide of formula (I) to obtain a ketazine of formula (III), followed by separation of the ketazine and acid hydrolysis. Method for preparing hydrazine:상기식에서, M은 알칼리토금속원자이고, R1및 R2는 각각 C1-C4알칼기이다.In the above formula, M is an alkaline earth metal atom, and R 1 and R 2 are each a C 1 -C 4 alkali group.제1항에 있어서 M가 바륨원자이고, 그리고 R1및 R2가 각각 메틸기임을 특징으로 하는 방법.The method of claim 1 wherein M is a barium atom and R 1 and R 2 are each methyl groups.제1항 또는 2항에 있어서, 유기용매가 메탄올임을 특징으로 하는 방법.The method of claim 1 or 2, wherein the organic solvent is methanol.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
