Abstract

The influence of ethanol, isopropanol and mixture thereof used during the polyanionic cellulose (PAC) manufacturing on the structure of alkali cellulose and PAC was studied by means of X-ray diffraction, microscope, ¹H-NMR and chemical titrimetry method. The result shows that the structure and property of alkali cellulose and PAC is hardly dependent on the organic solvent in the manufacturing process. With increasing of isopropanol, swelling ratio and adsorption quantity of cellulose base increase and crystalline grade of cellulose decrease, degree of substitution of the PAC and its solubility improve, and the distribution of the substituent in C₂, C₃, C₆ of the anhydroglucose unit (AGU) becomes more even.
