Abstract:

Lignonanocellulose has received extensive attention in various fields due to its simple preparation process, environmental friendliness, and high cost-effectiveness. Its production and application has become research hotspots in related fields. However, the aggregated structure of the lignocellulose and the complex chemical bonding (ether bond, ester bond, etc) between their components form an anti-depolymerisation barrier, which needs to be broken by pretreatment. Acid hydrotropes system has the advantages of high dissolution selectivity, easy separation of products, and recyclability, which is an important pretreatment method for the preparation and high value utilization of lignonanocellulose. This paper firstly introduces the concept and mechanism of acidic hydrotropes, then reviews the preparation methods and properties of lignocellulose with acidic hydrotropes, discusses the progress of functional application of lignocellulose, and finally summarizes the development of acidic hydrotropes. The deficiencies of the system are discussed, and the future research direction is prospected.

Key words: acid hydrotropes, hydrolysis, biomass, lignonanocellulose, nanomaterial, applications

摘要:

木质纳米纤维素因具有制备工艺简单、环境友好、成本效益高等特点而在各领域受到广泛关注,其制备与应用已成为相关领域的研究热点。然而,木质纤维组分间的聚集结构和复杂的化学键(醚健、酯键等)结合形成了抗解聚屏障,需要对其进行预处理破除屏障。酸性助水溶剂体系具有溶解选择性高、产物易分离、可循环利用等优点,是一种高效环保的绿色预处理工艺,是木质纳米纤维素制备及高值化利用的重要预处理方法。本文首先介绍了酸性助水溶剂的概念及作用机理,综述了酸性助水溶剂体系制备木质纳米纤维素的方法及性能,讨论了木质纳米纤维素的功能化应用进展,最后总结了酸性助水溶剂体系存在的不足,并对其今后的研究方向进行了展望。
