Bk. Barai et al., OPTIMIZATION OF A PROCESS FOR PREPARING CARBOXYMETHYL CELLULOSE FROM WATER HYACINTH (EICHORNIA CRASSIPES), Carbohydrate polymers, 32(3-4), 1997, pp. 229-231
alpha-Cellulose was isolated from water hyacinth (Eichornia crassipes)
, a free floating weed growing on shallow water. It was etherified wit
h chloroacetic acid in a solvent medium. The process of carboxymethyla
tion was optimized with respect to the solvent medium, alkali concentr
ation, acid concentration, time and temperature of the reaction. (C) 1
