一种固-液相变材料(PCM)：棕榈酸1，4-丁二醇二酯的微乳液合成与表征

Preparation and characterization of a solid-liquid PCM:1,4-butanediol di-palmitate

在水/DBSA/棕榈酸微乳液中,1,4-丁二醇和棕榈酸的直接酯化反应合成了一种固-液相变材料棕榈酸1,4-丁二醇二酯。并通过FT-IR,1H NMR和DSC对其进行了表征,DSC测试结果表明棕榈酸1,4-丁二醇二酯的峰顶温度为65.8℃,相变焓为162.4 kJ/kg。

1,4-Butanediol di-palmitate, a solid-liquid phase change material （PCM）, was prepared via the esterifieation reaction of palmitie acid with 1,4-butanediol in the water/DBSA/palmitie acid mieroemulsion 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 dipalmitate were at 65.8 ℃ and 162.4 kJ/kg,respeetively.
