【 摘 要 】

The theoretical calculation formula was used to predict the phase transition temperature and latent heat of the binary mixtures. Phase transition temperature and latent heat were experimentally studied by differential scanning calorimeter and compared with theoretical and experimental values. It is proved that the theoretical calculation formula was feasible to predict the phase change temperature and latent heat of fatty acid mixtures. Capric acid, stearic acid, myristic acid, palmitic acid and lauric acid organic phase-change materials were mixed to prepare binary mixtures. The results showed that the experimental data of phase transition temperature and latent heat of the binary mixtures were in good agreement with the theoretical ones. The results provide a reference and basis for the theoretical prediction of phase transition temperature and latent heat of phase transition for fatty acid mixtures.
