Carboxy methyl cellulose reaction principle

Chinese name: carboxy methyl cellulose
English name: carboxymethyl cellulose; CM-cellulose
Definition: cellulose, carboxymethyl group instead of the product. According to their molecular weight or degree of substitution, which can be completely dissolved or insoluble polymer, which can be used as weak acid cation exchange agent for separation of neutral or basic proteins. Applied science: Biochemistry and Molecular Biology (a subject); methods and techniques (two subjects)

Carboxymethyl cellulose, carboxymethyl cellulose group is replaced by the product. According to their molecular weight or degree of substitution, which can be completely dissolved or insoluble polymer, which can be used as weak acid cation exchange agent for separation of neutral or basic proteins. Carboxymethyl cellulose can form high viscosity colloid solution, there is adhesion, thickening, mobility, emulsifying, shaped, water, protective colloid, film forming, acid, salt, and other features for suspension, and no physiological harm, so in the food, pharmaceutical, chemical, petroleum, paper, textile, construction and other areas of production has been widely used.

Name and reaction principle
1 Chemical name: sodium carboxymethyl cellulose, carboxymethyl cellulose
Carboxyl Pinyin: suō
2 English name: Carboxyl methyl Cellulose
3 Abbreviation: CMC
Formula: [C6H7O2 (OH) 2CH2COONa] n
Reaction Principle
CMC is the main chemical reaction is generated cellulose and alkali and alkali cellulose alkalization reaction of alkali cellulose ether and an acid reaction.
The first step: alkaline: [C6H7O2 (OH) 3] n nNaOH → [C6H7O2 (OH) 2ONa] n nH2O
The first step: ether: [C6H7O2 (OH) 2ONa] n nClCH2COONa → [C6H7O2 (OH) 2OCH2COONa] n nNaCl
