摘  要:
本实验通过阿斯巴甜直接合成纽甜。在钯(Pd/C)氢化催化剂存在的情况下,阿斯巴甜与3,3-二甲基丁醛在甲醇溶液中经催化氢化合成、结晶、干燥,制得白色结晶纽甜。此方法条件温和,产品纯度高,收率可达到61%。

摘  要:
Neotame is a new type,high efficiency,non-nutrition sweetener.In this study,neotame was synthesized directly from aspartame.In the presence of hydrogenation catalyst Pd/C,aspartame and 3,3-dimethyl butyraldehyde were reacted in methanol solution.Then after crystallization and drying,white crystal neotame was obtained.This experiment was performed under mild conditions and high purity product with yield of 61% was obtained.
