First cellulose react with caustic to form alkali cellulose then react with mono chloro acetic acid or it’s salt from sodium carboxy methyl cellulose. During the reaction of alkali cellulose with etherification agents and in the subsequent reactions, sodium chloride (common salt) is produced as a major by-product. This is washed out together with any other byproducts or, in the case of technical-grade NaCMC, left in the product. The dried cellulose ethers are then processed into granular or powder products and in some cases modified with other additives. NaOH
Generally the reaction are as follows
Solvent Cellulose + caustic - alkali cellulose
Alkali cellulose + MCA ------ Na CMC + NaCl
