Preparation of sodium carboxymethyl cellulose from agricultural byproducts

Including cotton fiber, cassava fiber, straw fiber, bamboo fiber, wheat grass fiber and so on. However, with the continuous promotion of CMC in all walks of life. How to use cheaper and wider source raw materials for CMC preparation will surely become a concern under the existing raw material processing resources.

Sodium carboxylmethyl cellulose can used as emulsifier, flocculant, thickening agent, chelator, water retention agent, adhesive, slurry, film-forming materials, etc. Widely used in electronics, leather, plastic, printing, ceramics, daily chemical industry and other fields. And because of its excellent performance and a wide range of uses, is also constantly explore new application fields.

Now, uder the wide spread of the concept of green chemical production. The foreign research on CMC preparation process focuses on finding cheap and easy available biological raw materials. As a big country with agricultural resources, China has the advantages of raw materials in the cellulose modification process. But there are also various sources of biomass cellulose fiber. Ununiform preparation process caused by large differences in composition. At the same time, there are still deficiencies in improving the product grade, increasing the independent innovation of product types and development process, and the sufficient degree of utilization of biomass materials.
