摘要
铁、锌、钙、铜是人体必需的金属元素,其可以同二肽与氨基酸形成络合物,本文以阿斯巴甜与金属盐为原料,研究了阿斯巴甜铁、锌、钙以及铜螯合物的合成方法,并通过络合滴定测定了其螯合率,红外光谱对产品进行了分析鉴定。
Iron,zinc,autunite and copper are necessary metal elements of human body.They often form complexes with dipeptide and amino acid.The thesis introduced the procedure of synthesizing aspartame iron, zinc, autunite and copper complex with the raw material of aspartame and metal salt.In the mean time, the chelation ratio was determined by complexometric titration and the products were analyzed and confirmed by IR spectrometry.
