| 摘 要： | 采用微波辐射技术,以壳聚糖和双氰胺为反应原料,合成了一种壳聚糖双胍盐酸盐抗菌剂。利用红外光谱、核磁谱图和扫描电镜对产物的结构进行了表征,并通过正交实验设计考察了不同反应溶剂、微波辐射功率、微波辐射时间等因素对产率和胍取代度的影响。结果表明,最佳合成反应条件为:微波采用高档辐射功率,反应溶剂为0.15mol/L盐酸,微波辐射时间15min。采用微波辐射合成壳聚糖双胍盐酸盐抗菌剂,反应速度是传统常规法的12倍,在极短的时间内获得几乎和传统合成方法同样的产率,极大地节约了时间、提高了效率。

| Abstract: | Antimicrobial chitosan biguanidine hydrochloride has been synthesized by the guanidineylation reaction of chitosan with dicyandiamide under microwave irradiation. The products were analyzed by infrared spectrum,13 C NMR and scanning electron microscopy. Effects of the reaction solvents,microwave irradiation power and microwave irradiation time on the reaction yield and substitution degrees of guanidinylated chitosan were investigated by using orthogonal experimental design. The optimal condition for the rea... |
