【摘要】 研究糖－缩氨基脲衍生物的合成，对确定特定的单糖或双糖是有价值的．选用乙酸钠调节ｐＨ值，因糖与盐酸氨基脲反应，合成糖－缩氨基脲衍生物，并通过熔点、元素分析，红外光谱与紫外光谱对合成的化合物进行了表征．又通过反应机理的详细阐述，较好地解释了一些实验事实．更多还原

【Abstract】 This paper studyed the synthesic of sugar condensed amino urea derirative. It is Valuable of telling monosauharide from oligosaccharride. Sodium acetate be used in charging the number of pH. Sugar and semicarbazide hydrochloride are used to synthesize sugar condensed amino urea deriative all complexes heve been characterized by melting point. elementary aralysis. IR and UV. The article states reaction in detail and explains many experiment cases .更多还原
