To determine the thermal properties of eutectic mixture of fatty acids by theoretic calculations, a formula of predicting thermal properties of eutectic mixture was selected and validated, and then the melting temperature and latent heat of eutectic mixture of fatty acids were calculated. From the calculation, the result of the theoretic calculation agrees well with that of the previous experiments. For the 15 eutectic mixtures of fatty acids, the minimum and maximum of the melting temperature are (10.2 and 51.5) 掳C, respectively. The minimum and maximum of the latent heat are (138.6 and 187.5) J路g^鈥?, respectively. The eutectic mixtures of fatty acids are suitable for heating, a heat water system, phase wallboard, concrete and phase clothes, and other engineering applications.
