Аннотация: Samples of microcrystalline cellulose (MCC) have been studied by X-ray photoelectron spectroscopy before and after sulfation. It has been found that the reaction of MCC with chlorosulfonic acid in dioxane results in the incorporation of sulfate groups into the structure of cellulose. The content of sulfur in sulfated MCC varies froПоказать полностьюm 4.0 to 9.7 at %, sulfur being in the form of sulfate. The sulfur content on the surface and in the bulk of MCC sulfate samples has been compared. The difference in the shape of is lines of carbon in the spectra of initial and sulfated MCC samples indicates that the electron state of a fraction of the carbon atoms undergoes changes during sulfation.
