Abstract:
Erythritol is a latent heat storage material suitable for the utilization of unused heat in the medium temperature range of 100-250 °C. However, the supercooling characteristic of sugar alcohols reduces the energy utilization efficiency. In this study, erythritol and its fluorine analogues are mixed to suppress supercooling. Erythritol mixed with 2,3-difluorobutane-1,4-diol at a weight ratio of 1% is determined to be effective in suppressing supercooling. This indicates the possibility of utilizing energy more efficiently.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
