Pinacone hexahydrate, a glycol hydrate, has a comparably high melting enthalpy of about (316 +/- 16) J.g(-1) at 45.5 degrees C. Based on results of a previous study and to further assess the applicability of pinacone hexahydrate to be used as phase change material in latent heat storage systems, additional investigations were carried out in this work. First, the influence of a deviation of the water content around the stoichiometric hexahydrate composition on the melting enthalpy was investigated. It was less pronounced compared with typical inorganic salt hydrates. Second, the crystallization velocity was measured as a function of temperature with a maximum value of about 0.5 cm.min(-1) at 27 degrees C. Third, tests of the thermal cycling stability were carried out. Within 110 conducted cycles between 20 degrees C and 60 degrees C, the melting enthalpy and temperature remained stable.
