甘露低聚糖与铜(Ⅱ)配合物制备工艺的研究

STUDY ON PREPARATION OF THE COOPERATION OF MANOLIGOSACCHARIDES AND COPPER(Ⅱ)

以甘露低聚糖与氯化铜为原料制备了甘露低聚糖铜(Ⅱ)配合物.以甘露低聚糖铜(Ⅱ)配合物中铜离子的含量为考察指标,通过正交试验,考查了反应时间、pH值、反应温度等因素对产物的影响,运用紫外光谱(UV)和红外光谱(IR)对产物进行了表征.结果表明:反应时间为108 min、温度为54℃、pH为6.4、0.1 mol/L的氯化铜加入量为21 mL时,产物的得率最高,甘露低聚糖与铜离子发生结合的部位在羟基上.

This article uses the manoligosaccharides and copper chloride to compose of MOS- Cu（ Ⅱ） complexation and discuss the influential factors of complex MOS-Cu （ Ⅱ ）, such as reaction time, pH, reaction temperature and so on. Meanwhile, the complex was detected by UV and IR to check its symbol. The result indicates that the better method to compound the MOS-Cu（Ⅱ ） complexation is the reaction time 108 min, pH 6.4, the reaction temperature 54 ℃ and the volume of 0.1 mol/L copper chloride 21 mL and that Cu（ Ⅱ ）was interacted with -OH of MOS.
