摘　　要：用2,3-环氧丙基三甲基氯化铵对壳聚糖进行改性,采用不同反应条件制备了一系列不同取代度的羟丙基三甲基氯化铵壳聚糖(HACC)。通过红外光谱、核磁共振光谱对结构进行表征,IR谱图分析证实以N上取代为主。研究了产物的取代度、吸湿与保湿性、抗菌性、pH稳定性、与表面活性剂的配伍性。A series of 2 - Hydroxypropyltrimethyl ammonium chloride chitosan with different degree of substitution were prepared by the reaction of chitosan with 2,3 - epoxypropyltrimethyl ammonium chloride. Structure of HACC was characterized by infrared spectrum and 13C NMR, and it is proved that substitution reaction mainly occurs on the -N element. Its DS, hydroscopicity, moisture retention, antibacterial activity, pH stability and its compatibility with other surfactants are studied.
