Dissolution method of sodium antelope methylcellulose
2024.01.23
Sodium methylcellulose is a water-soluble polymer compound commonly used in the preparation of colloids, nanomaterials, and pharmaceuticals. Below are several dissolution methods for sodium antelope methylcellulose
1. Water dissolution method: Gradually add the sodium carboxymethyl cellulose powder to the water stirred at room temperature, being careful not to pour it directly into the water to avoid clumping. Wait for a moment, stir evenly to obtain a clear solution
2. Strong alkaline dissolution method: The sodium carboxymethyl cellulose powder is gradually added to a solution containing sodium hydroxide. An appropriate amount of sodium hydroxide can promote the dissolution of sodium carboxymethyl cellulose. However, it should be noted that the amount of sodium hydroxide should not be too much to avoid forming a concentrated solution and losing its viscosity
3. Water/ethanol dissolution method: Add sodium carboxymethyl cellulose powder to water and ethanol separately, stir until fully dissolved, and then mix the two solutions to obtain a stable solution.
4. Special dissolution methods: Different special dissolution methods can be used according to the different structures and uses of sodium methylcellulose. For example, surfactants or organic solvents can be used for dissolution. Selection and control of usage needs to be based on actual situations
