摘要

分别采用超声波、微波、N

N一二甲基乙酞胺( DMAc)和四氢吠喃(THF)对芦苇浆粕进行预处理，并以此为原料采用稀盐酸水解法制备芦苇微晶纤维素(MCC).利用X射线衍射}XRD)、红外光谱AFT - IR)和热失重分析(TGA)等测试方法对MCC的结构性能进行表征与分析.结果表明:芦苇浆粕按以上4种方法预处理后，经稀盐酸水解制备的MCC的结晶度分别为68. 45%

62.28%

63. 21%和69. 56%.与其他3种预处理方法相比，经超声波预处理后水解制备的MCC的热稳定性最优，同时产率最高.为MCC的进一步研究和应用打下基拙.

Abstract

Reed cellulose pulp was pretreated by ultrasonic，microwave，N，N一dimethylara acetamide(DMAc ) and tetrahydrofuran(THF)，respectively. Reed microcrystalline cellulose(MCC)was prepared by thedilute hydrochloric acid hydrolysis from the reed which pretreated by different methods. The structure and propertiesof MCC were characterized by XRD，FT-IR and TGA. The results showed that the crystallinity of MCC with fourpretreatment methods was 68. 45 %，62. 28 %，63.21 and 69. 56%，respectively. The thermal stability of MCCprepared by hydrolysis after pretreated by ultrasonic was the best compared with other three methods. The yield ofMCC with ultrasonic pretreatment was the highest. The foundation for the further research and application of MCCwas laid.
