title: [Thermoanalytical studies of sodium salt of carboxymethylcellulose (CMC-Na) and pectin].
abstract: The influence of physical and chemical properties of electrolytes on thermal degradation of CMC-Na and pectiny salt were studied. A differential thermal analysis showed that thermal decomposition of CMC-Na and pectin salt proceeds in three stages. The heat of conversion of the studied systems was shown to increase according to the concentration of the applied electrolytes. Significant changes in the structure of CMC-Na at pH = 3.0 were shown by IR analysis. Confirmation of transition of the above system to the acidic form were obtained by DTA and TG curves.
