Preparation and characterization of a novel solid-liquid PCM: Butanediol di-stearate

Butanediol. di-stearate, a novel solid-liquid phase change material, was prepared via the reaction of thionylchlorided stearic acid with 1, 4-butanediol. And then it was characterized by FT-IR, H-1 NMR spectra and DSC measurements. The DSC results indicate that the phase change onset temperature and phase change enthalpy of butanediol di-stearate were at 41.80 degrees C and 181.97 kJ/kg, respectively. (c) 2006 Elsevier B.V.
