生物质基羧甲基纤维素制备与应用新进展
New progress in preparation and application of biomass-based carboxymethyl cellulose
从制备羧甲基纤维素(carboxymethyl cellulose,CMC)的生物质原料出发,介绍了制备CMC的非粮生物质原料。根据CMC制备工艺过程,分别对生物质纤维素提取、碱化和醚化工艺、CMC表征及改性进行了综述。使用绿色溶剂预处理是提取纤维素的发展方向;碱化、醚化工艺采用溶液法有助于制备高性能产品,通过工艺创新可制备高取代度、高黏度CMC;进一步采用物理、化学改性可提高产品性能。在此基础上,综述了CMC在农业、环境、医疗、新能源等领域的创新应用,分析了CMC应用新趋势,展望了CMC在不同领域的应用前景。
Non-food biomass feedstocks for carboxymethyl cellulose (CMC) preparation are firstly introduced from biomass feedstocks for CMC preparation.According to the CMC preparation process,the extraction,alkalization and etherification processes for biomass cellulose,as well as the characterization and modification of CMC are reviewed,respectively.The use of green solvent pre-treatment method is the development direction for the extraction of cellulose.Using solution method in alkalization and etherification processes helps to prepare high-performance products.CMC with high substitution and high viscosity can be prepared through process innovation.Further physical and chemical modification can improve products’ performance.On this basis,the innovative applications of CMC in agriculture,environment,medical treatment,new energy and other fields are reviewed,new trends for CMC application are expounded,and the prospects of CMC applications in different fields are envisioned.
