| Abstract | ||
| Sodium carboxy methyl cellulose with three different degree of substitution that valued 0.65, 0.70 and 0.95 were prepared by alkalification and esterification of bacterial cellulose produced by Acetobacter xylinum 48 with monochloro acetic acid under different conditions. The molecular weight of three samples of Sodium carboxy methyl cellulose were 557000, 615000 and 699000 gm/mol, while their viscosity were 5100, 6250 and 8500 centipoises, with a purity of 99.71, 99.65, 99.60% and moisture content of 5.5, 6.0, 7.5%, respectively. The study revealed that the best pH was ranged between 7-9 for solubility of bacterial Sodium carboxy methyl cellulose with degree of substitution 0.7 . | ||
