摘要：

Characterization of an Avicel PH 102 MCC powder through polymerization degree determination, X-ray diffraction and N-2 adsorptions at subcritical temperatures is described. Specific characterizations of MCC/H2O exchange in different environments were performed by means of thermogravimetric weight losses on time/temperature scale and analyses of water adsorption/absorption from saturated vapors at 310 K. The reversibility of MCC/H2O interactions and the influence of different 'surface area probes' on the specific surface area are discussed.
