Uses and synthesis of Sodium carboxymethyl cellulose powder

Sodium carboxymethyl cellulose powder is a carboxymethylated derivative of cellulose, also known as cellulose gum, an anionic cellulose ether, Sodium carboxymethyl cellulose CAS 9004-32-4 is the most important ionic cellulose gum.

Sodium carboxymethyl cellulose Raw Materials is a kind of anionic polymer compound which is usually produced by reacting natural cellulose with caustic soda and monochloroacetic acid.

Applications / Functions of Sodium carboxymethyl cellulose powder

• Sodium carboxymethyl cellulose powder is widely used as thickener, suspending agent, binder, protective colloid, etc. in pharmaceutical, daily chemical and food industries.
• Used in oil drilling, textile printing and dyeing
• Sodium carboxymethyl cellulose CAS 9004-32-4 Used as mud stabiliser for oil and gas drilling, textile slurry, paper reinforcement, adhesive, etc.
• Sodium carboxymethyl cellulose powder is used for washing, cigarette, construction, daily-use chemical industry.

Used in textile sizing, drilling, etc.

Used as water-based drilling fluid filtration loss reduction agent, with a certain viscosity increasing effect.

Sodium carboxymethyl cellulose Raw Materials can be used in pulp as reinforcing agent, also used for surface sizing, used as viscosity adjusting agent in coated processed paper.

Physicochemical Property of Sodium carboxymethyl cellulose powder

White or light yellow fibrous powder, odourless and tasteless. Easily dispersed in water as transparent colloid, insoluble in organic solvents such as ethanol, acetone and ether.

Production methodprocess of Sodium carboxymethyl cellulose powder

• Usually take refined cotton as raw material, react with sodium hydroxide to produce alkali cellulose, then carboxymethylate with chloroacetic acid to produce Sodium carboxymethyl cellulose CAS 9004-32-4.
• Spray 18%~19% of lye into the kneader, alkalise the refined cotton to produce alkali cellulose at 30~35℃, then knead and etherify with solid sodium chloroacetic acid. The first 1 ~ 2h temperature control below 35 ℃; after 1h temperature control at 45 ~ 55 ℃. After a period of maturation (so that the etherification is complete), it is dried and crushed to obtain Sodium carboxymethyl cellulose Raw Materials.
