1,4-Butanediol di-palmitate,a solid-liquid phase change material(PCM),was prepared via the esterification reaction of palmitic acid with 1,4-butanediol in the water/DBSA/palmitic acid microemulsion system.And then it was characterized by FT-IR,~1H NMR spectra and DSC measurements.The DSC results indicate that the phase change onset temperature and phase change enthalpy of 1,4-butanediol di-palmitate were at 65.8 ℃ and 162.4 kJ/kg,respectively. |
