What is Cellulose Gum?
Cellulose gum (carboxymethyl cellulose or CMC) is derived from natural cellulose through an alkali-catalyzed reaction with chloroacetic acid. This modification process transforms natural cellulose into a water-soluble polymer with unique functional properties. The compound's versatility stems from its ability to maintain stability across different pH levels (typically 3-10) and temperature ranges (-20°C to 100°C).
Manufacturing Process
Primary Production Steps
1. Alkalization
- Raw cellulose is treated with sodium hydroxide
- Creates reactive sites on cellulose molecules
- Temperature control crucial (20-30°C)
2. Etherification
- Reaction with monochloroacetic acid
- Determines degree of substitution (DS)
- Process variables affect final product quality
3. Purification
- Multiple washing stages remove by-products
- Filtration removes insoluble particles
- Quality of water affects final purity
4. Drying and Milling
- Controlled drying prevents degradation
- Particle size classification
- Packaging under controlled conditions
Critical Control Points
- Temperature monitoring during reactions
- pH control during purification
- Particle size distribution
- Moisture content in final product
