Abstract
Interaction of cellulose samples with dimethylsulfoxide, ethanol and water and organic liquids on their basis was studied with the methods of calorimetry and effusion depending on the content of the organic component. The dependence of the enthalpy of the interaction of the cellulose with individual and mixed liquids was analyzed. The same dependence was analyzed for liquid sorption as a function of liquid content in the amorphous regions of the polymer and the composition of the mixed liquor. The specific heat of adsorption of water, DMSO and ethanol with various cellulose samples was determined. The equation was proposed for estimating the enthalpy of the interaction of different types of cellulose with a liquid and its maximum sorption.
