- Abstract
Composition and structure of microcrystalline cellulose (MCC) sulfates obtained by traditional and new advanced methods of MCC sulfation were compared. Data on the composition and structure of MCC sulfates synthesized in the medium of chlorosulfonic acid –1,4-dioxane and by sulfation of MCC with sulfamic acid in the presence of urea in N,N-dimethylformamide and diglyme were obtained with the use of elemental analysis, FTIR, Raman, 13C NMR, XRD, XPS, SEM and AFM methods. It was shown that MCC sulfates synthesized by new methods have more homogeneous composition and morphology as compared to sulfates obtained by known methods
