以壳聚糖与硬脂酰氯反应合成酰化壳聚糖。通过傅里叶变换红外(FTIR)、H-1核磁共振(H-1 NMR)光谱、X射线衍射(XRD)和热重(TG)技术证实了所制备化合物的化学结构和物理性质。通过H-1 NMR计算取代度(DS)并且范围为1.8至3.8。合成的化合物在有机溶剂中表现出优异的溶解度。 XRD分析表明它们具有高结晶结构。 TG结果表明所制备的化合物的热稳定性低于壳聚糖，失重随着DS的增加而减小。该过程可能是制备有机可溶性壳聚糖衍生物的简便方法。 (C) 2008 年，爱思唯尔有限公司出版。
Acylated chitosan was synthesized by reaction of chitosan and stearoyl chloride. The chemical structures and physical properties of the prepared Compounds were confirmed by Fourier transform infrared (FTIR), H-1 Nuclear Magnetic Resonance (H-1 NMR) spectroscopy, X-ray diffraction (XRD) and Thermogravimetric (TG) techniques. The degree of substitution (DS) was calculated by H-1 NMR and ranged from 1.8 to 3.8. The synthesized compounds exhibited an excellent solubility in organic solvents. XRD analysis showed that they had high crystalline structure. TG results demonstrated that thermal stability of the prepared compounds was lower than that of chitosan, the weight loss decreased with increase of DS. This procedure could be a facile method to prepare organic-soluble chitosan derivatives. (C) 2008 Published by Elsevier Ltd.
