羧甲基纤维素钠(CMC)是天然纤维素经改性后的衍生物,是应用领域宽广、种类繁多、生产量大、研究价值高的多功能纤维素衍生产品.棉花和木浆是制备CMC的主要原料,因其需求越来越大,经常处于供不应求境况.因此,开发其他资源丰富、来源广泛、廉价的纤维素原料制备CMC具有较高研究价值和应用前景.文章就利用废弃生物质为纤维素原料制备CMC的研究进展、CMC的应用领域与前景展望等进行综述. Carboxymethylcellulose sodium (CMC) is a natural cellulose modified derivatives, is a wide range of applications, a wide range of large volume, high research value of multifunctional cellulose derivatives.Cotton and wood pulp is the preparation The main raw material of CMC, because of its increasing demand, is often in short supply situation.Therefore, it is of high research value and application prospect to develop CMC which is rich in other resources, widely available and inexpensive.However, The research progress of preparation of CMC for cellulosic raw materials, the application field and prospect of CMC are summarized.
