Phase separation material essentially influence storage capacity or heat release. Ricinoleic acid is potential to be used as a heat storage material. However, the nature of the phase separation of the material has not been studied yet. Therefore, this research was aim to determine the nature of the material. The test of characteristics of heat fusion and crystallization temperature of the material are carried were examined by using differential scanning calorimetry (DSC). The test was carried out using 15-20 mg of ricinoleic acid with cooling rate of 2°C/min, 3°C/min, 4°C/min, 5°C/min, 10°C/min, and 15°C/min. Coagulation testing was done by using a digital microscope of data aquisition. For comparison, characterization on oleic acid was also done. The result that hydroxyl functional group affects the occurrence of phase separation on the ricinoleic acid freezing process.
