| Property | Details |
|---|---|
| Chemical Name | Carboxymethyl cellulose (CMC) |
| Synonyms | Carboxymethyl ether cellulose, cellulose carboxymethyl ether, CMC - 4 LF, Carbose, etc.1 |
| CAS Number | 9000 - 11 - 71 |
| EINECS Number | 618 - 326 - 22 |
| Molecular Weight | Variable, depending on the degree of polymerization and substitution. The molecular weight of the monomer unit is about 240.2061 |
| Appearance | White or slightly yellow fibrous powder or granular solid, odorless and tasteless1 |
| Density | 1.050 g/cm³ (at 15 - 18 °C)2 |
| Melting Point | Not applicable (decomposes at high temperatures) |
| Boiling Point | 527.1 °C at 760 mmHg1 |
| Flash Point | 286.7 °C1 |
| Vapor Pressure | 2.59 e - 13 mmHg at 25 °C1 |
| Solubility | Soluble in water, forming a colloidal solution with a certain viscosity. Insoluble in anhydrous ethanol, methanol, and other organic solvents. Swells in water to form a suspension and becomes viscous in 1 M sodium hydroxide2 |
| Stability | Stable under normal conditions. Combustible. Incompatible with strong oxidizing agents. Prone to degradation under the action of cellulase and amylase. The carboxymethyl group can bridge with multivalent metal ions. In the presence of alkali, it can undergo an oxidation reaction with chlorinating agents such as iodate, nitrogen dioxide, hypochlorite, and hydrogen peroxide, causing the main chain to break and the viscosity to decrease. In the presence of an acid catalyst, it is prone to hydrolysis, leading to the breakage of the main chain and a decrease in the degree of polymerization1 |
