Claims (3)

메탄올을 반응용매로 하여 아스파트산의 염을 30분간 완류하여 실온으로 냉각하고 아세틸아세톤-메탄올 혼합액을 첨가한 다음 3시간동안 환류하고 반응용매를 감압증류하여 황색의 잔유물을 얻은 후, 이에 물을 첨가하고 산으로 pH 2.5로 조정하여 L-N-(1-메틸-2-아세틸-비닐)-아스파트산을 제조하는 방법.Methanol was used as a reaction solvent, the salt of aspartic acid was completed for 30 minutes, cooled to room temperature, acetylacetone-methanol mixed solution was added, refluxed for 3 hours, and the reaction solvent was distilled under reduced pressure to obtain a yellow residue. Process of adding LN- (1-methyl-2-acetyl-vinyl) -aspartic acid by addition and adjustment to pH 2.5 with acid. 제 1 항에 있어서, 아스파트산과 메탄올의 몰비는 1 : 22.0 이며, 아스파트산과 아세틸아세톤의 몰비는 1 : 1.1, 아세틸아세톤-메탄올 혼합액의 아세틸아세톤 : 메탄올 몰비는 1 : 6.7 임을 특징으로 하는 L-N-(1-메틸-2-아세틸-비닐)-아스파트산의 제조방법.The molar ratio of aspartic acid to methanol is 1: 22.0, the molar ratio of aspartic acid to acetylacetone is 1: 1.1, and the acetylacetone: methanol molar ratio of acetylacetone-methanol mixture is 1: 6.7. Method for preparing-(1-methyl-2-acetyl-vinyl) -aspartic acid. 제 1 항에 있어서, 아스파트산의 염은 포타슘염 또는 소디움염임을 특징으로 하는 L-N-(1-메틸-2-아세틸-비닐)-아스파트산의 제조방법.The method for preparing L-N- (1-methyl-2-acetyl-vinyl) -aspartic acid according to claim 1, wherein the salt of aspartic acid is potassium salt or sodium salt. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
