Elimination Processes of Guest Molecules from the Inclusion Compounds of Deoxycholic Acid

抄録

Thermal behaviors of the inclusion compounds of deoxycholic acid with methanol, ethanol, propane-1-ol, propane-2-ol, and butane-1-ol have been studied by TG-DTA-MS and DSC. Liberation processes of guest molecules from their inclusion compounds of methanol, ethanol were carried out in a single step. Those of propanols and butane-1-ol from the corresponding inclusion compounds proceed in complicated steps. The elimination temperatures, enthalpies and the activation enthalpies of eliminations have been determined by TG, DSC, and MS.
