| 摘 要： | 以壳聚糖和樟脑酸为原料，在微波辐射下合成了一种新型壳聚糖衍生物——樟脑酸酰化壳聚糖，通过红外（FT-IR）、核磁（1H—NMR）、X-射线衍射（XRD）和热失重（TG）等测试手段对产物结构和性能进行了表征。结果表明樟脑酸通过酰胺键与壳聚糖结合，X-射线结果表明樟脑酸酰化壳聚糖的晶体结构发生了很大的改变，TG分析表明其热稳定性好于壳聚糖。 |
| 关 键 词： | 壳聚糖 樟脑酸 热稳定性 晶体结构 |

| Abstract: | A new type chitosan derivative,camphoric acid chitosan amide,was synthesized by using of chitosan and camphoric acid as raw materials under microwave irradiation.The chemical structures and properties of the target product were investigated by fourier transform infrared(FT-IR),proton nuclear magnetic resonance spectra(1H-NMR),thermogravimetric analyses(TG),and X-ray diffraction(XRD)measurements.The results showed that the camphoric acid is bonded with chitosan by amide-bond.The XRD pattern of product is signicantly different from the crystalline structure of chitosan.TG result demonstrated that thermal stability of the product is better than that of chitosan. |
| Keywords: | Chitosan Camphoric acid Thermal stability Crystalline structure |
