| 摘 要： | 在微波辐射下,以壳聚糖和歧化松香为原料,首次合成了一种新型壳聚糖衍生物———歧化松香酰化壳聚糖(DR-CA),并通过红外、紫外、X射线衍射、扫描电镜、元素分析和热分析等测试手段对产物进行了结构和性能表征。系统研究了溶剂、物料配比(r)、温度、时间和微波功率对取代度(DS)的影响。结果表明,当r为6∶1时,在含吡啶约50%(体积比)的DMF溶液中,微波功率800 W下,100℃反应2.5 h获得了最高取代度的DRCA(DS=0.165)。溶解性试验表明,DRCA具有较好的水溶性,且从DRCA的临界胶束浓度(CMC)(CMC=0.003 g/mL,此时表面张力为σCMC=55.22 mN/m)可知,所合成的DRCA具有一定的表面活性。

| Abstract: | A new type of chitosan derivative,disproportionated rosin chitosan amide(DRCA),was synthesized by using chitosan and disproportionated rosin as raw materials under microwave irradiation.The target product was characterized by FT-IR,UV,XRD,SEM,DTA/TG and elemental analysis.The effects of solvent,mole ratio of disproportionated rosin chloride to the amino groups of chitosan(r),time, temperature and microwave power on the degree of substitution(DS) of DRCA were investigated,and the optimum synthetic conditions... |
