CMC Sodium Salt, CMC-Na :
It is an important water-soluble cellulose derivative, and its chemical properties mainly depend on the carboxymethyl substitution degree (DS, usually 0.6-1.2) and molecular chain structure. The following is a detailed analysis of its key chemical properties:
1. The solubility of water-soluble: CMC - Na soluble in cold water or hot water, forming a transparent viscous solution, solubility increases with substitution degree (DS) increased. Water solubility is significant when DS ≥ 0.4. PH dependency: 4-12 in the pH range solubility stability; Free carboxylic acid (CMC-H) may precipitate when pH is less than 4, and degradation may occur when pH is greater than 12. Organic solvents, insoluble in ethanol, and other organic solvents, but can tolerate a certain percentage of ethanol - water mixing system (e.g., less than 60%) .
2. The ionization and ion exchange polyelectrolyte behavior: CMC - Na in the water dissociation for Na ⁺ and negatively charged carboxymethyl cellulose anion (R - COO ⁻), presents the polyanion features. Ion exchange: Na ⁺ can be other metal ions, such as Ca squared ⁺, Al after ⁺) replacement, generate insoluble salt (such as CMC, Ca), but high metal ions may cause crosslinking or gelation .
3. The viscosity characteristics influence factors: concentration: viscosity with the increase of concentration of exponential rise (non-newtonian fluid behavior). Temperature: temperature will temporarily reduce viscosity, but long time high temperature (> 80 ° C) may result in the degradation. PH: neutral conditions the highest viscosity, acid/alkali environment can destroy the molecular chain. Salt effect: high concentration of salt (NaCl) can shield charge, reduce the viscosity.
4. The chemical stability of acid sensitivity: pH < 3, carboxymethyl hydrolysis (- ⁻ COO - - -cooh) group, resulting in a decline in precipitation or viscosity. Oxidative degradation: strong oxidizer (such as sodium hypochlorite) fracture beta - 1, 4 - glycosidic bond, the molecular weight decreased. Thermal stability: short-term tolerance below 80 ° C; Long-term high-temperature or dry heating (>200°C) will cause coking.
5. The esterification reaction activity/crosslinking: with polyvalent metal ion (Al after ⁺), epoxy chloropropane, such as crosslinking, forming gel or film. Grafting modification: under the effect of initiator, with acrylic acid, styrene monomer graft copolymerization, giving new features.
6. The interaction of protein with other substances: through electrostatic interactions with positively charged proteins form compounds (such as gelatin). Surfactant: with anionic surfactant (SDS) thickening, it has good compatibility with nonionic. Polysaccharides: synergy with xanthan gum and carrageenan viscosity increasing effect.
7. Biodegradability digestion: cellulase can slow degradation of CMC - Na, but the rate is lower than natural cellulose (because of substituent hinder enzyme action). Environmental degradation: in the soil or water by microbial decomposition of CO ₂ and H ₂ O.
