Abstract

The influence of the solvent system used during the CMC manufacturing on the characteristics of CMC in different solutions was studied by producing CMC in ethanol, isopropanol or a mixture thereof. This paper shows that the solvent system used has an impact on the substituent pattern and this is especially the case during the mercerisation. When isopropanol is used in comparison with ethanol the distribution of the substituents along the cellulose backbone becomes more uneven and the amount of tri-substituted glucose units increases as well as the number the amount of substituents on the C-6 position. This affects the behaviour of CMC when dissolved in different electrolyte solutions.
