摘要
纤维素是自然界中一种非常丰富的天然高分子化合物。纤维素的溶解是将这种可再生资源有效转化为高附加值产品的关键步骤,其溶解体系所用溶剂分为衍生化溶剂和非衍生化溶剂。从这两方面简要介绍纤维素的溶解体系及其机制,并对各个溶剂体系的优缺点进行简要概述,预测未来纤维素溶解体系会朝着高效、节能、环保的方向发展。
Cellulose is a very abundant natural polymer compound in nature.The dissolution of cellulose is a key step to effectively transform this renewable resource into high value-added products.The solvent used in its dissolution system is divided into derivatized solvent and non-derivatized solvent.From these two aspects,the cellulose dissolution system and its mechanism are briefly introduced,and the advantages and disadvantages of each solvent system are briefly summarized.It is predicted that the cellulose dissolution system will develop in the direction of high efficiency,energy saving and environmental protection in the future.
