摘要：

Esterification of different commercial mixtures of stearic and palmitic acid with methyl, butyl and propyl alcohols was undertaken at the laboratory scale and the thermal properties of the esters were determined by Differential Scanning Calorimetry (DSC). Twelve products were obtained with melting points in the interval of 17-34 degrees C and freezing points in the range of 20-32 degrees C. About half of them are characterized by a latent heat of transition of 140-150 J/g and the other half by a latent heat of transition of 180-190 J/g. Even at the incipient phase, research concerning the esterification of different commercial grades of stearic acid has demonstrated the ability to tailor PCM's with specific transition temperature.
