On The Preparation Of CMC

As the application ofcarboxymethyl cellulose (CMC) continues to expand, the preparation methods of CMC are also constantly studied. At present, the traditional chemical method is widely used to prepare carboxymethyl cellulose. Probably the process is to replace the fiber derivatives with carboxymethyl and then use sodium hydroxide, commonly known as caustic soda or caustic soda, to treat the cellulose and form alkali cellulose after treatment. The final operation requires the participation of monochloroacetic acid, which reacts with the preceding products, and finally, a crude CMC can be obtained.

The CMC obtained by this method needs further refinement, but it is not difficult. Now some people begin to use beet seed to prepare CMC. The specific operation is relatively complex, and the principle is based on chemical reaction, and after the development, it also needs a refinement process. There will be more methods for the preparation of CMC, and different new methods will play a very good role in promoting the preparation of a large number of CMC. More formulation methods will emerge as CMC continues to expand its application.
