Effect of Mixing Erythritol and Its Fluorine Analogues to Suppress Supercooling.

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.
