Carboxymethyl Mass

The main indicators of CMC quality are degree of substitution (DS) and purity. Generally speaking, the properties of CMC are different when different DS is different. The degree of substitution increases, and the solubility increases, and the transparency and stability of the solution are also better. It is reported that when the degree of substitution of CMC is between 0.7 and 1.2, the transparency is good, and the viscosity of aqueous solution is the largest when pH value is 6~9. In addition to the selection of etherification agent, some factors that affect the degree of substitution and purity must be considered, such as the relation between the dosage of alkali and etherification agent, the time of etherification, the water content of the system, the temperature, the pH value, the concentration of the solution and the salt and so on.
