%X A water desorption process of a mixture of room temperature ionic liquid (N, N-diethyl-N-methyl-N-(2-methoxyethyl) ammonium tetrafluoroborate) and water was investigated via simultaneous X-ray diffraction and differential scanning calorimetry (DSC) measurements, in which relative humidity was controlled by a water vapor generator. In these measurements, H2O concentration was estimated by the peak position of the principal peak in X-ray diffraction patterns, and the thermal property associated with a mixing state was detected by a DSC thermograph. In addition, the density of the mixture was measured as a macroscopic property. In situ observations revealed that the thermally unstable mixing state in the water-rich region has an important correlation with density and thermal and structural properties.
