Effect of Mixing\nErythritol and Its Fluorine Analogues\nto Suppress Supercooling

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