Abstract: This paper described the preparation of xanthation chitosan (XCTS) by the conventional and ultrasonic methods. The elemental analysis, FT-IR, XRD, SEM and TG were adopted to characterize the structure of the products. In addition, the effects of material ratio, ultrasonic power, reaction temperature, reaction time and alkali concentration on the prepared XCTS were studied. The results showed that ultrasonic method could significantly speed up the preparation process and increase its production, as well as increasing the sulfur content of products. The optimum conditions for preparation were as follows:the mass ratio of chitosan to carbon disulfide was 1:2; the ultrasonic power was 150W; the ultrasonic time was 60min, and NaOH solution was of 15%.

Key words: chitosan, xanthation chitosan, ultrasonic, radiation, synthesis, multiphase reaction

摘要: 介绍了制备黄原酸化壳聚糖(XCTS)的常规方法和超声波法, 使用元素分析、FT-IR、XRD、SEM和TG对其结构进行表征, 并分析了物料比、超声波功率、反应温度、反应时间和碱浓度对超声波法制备XCTS的影响。结果表明超声波法能明显加快制备黄原酸化壳聚糖的速度, 增加产量, 同时提高产物的硫含量, 其最佳工艺:壳聚糖与二硫化碳的质量体积比为1:2(g/mL), 超声波功率为150W, 超声波作用时间为60min, NaOH的质量分数为15%。
