본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (3)

  1. 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.
  2. 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.
  3. 제 1 항에 있어서, 아스파트산의 염은 포타슘염 또는 소디움염임을 특징으로 하는 L-N-(1-메틸-2-아세틸-비닐)-아스파트산의 제조방법.
