Liquid-solid phase transformation of C16H34, C28H58 and C41H84 and their binary and ternary mixtures

Differential scanning calorimetry (DSC) was used to study the phase transfo rmations of three pure n-alkanes, namely hexadecane (C16H34), octacosane (C 28H58) and hentetracontane (C41H84), and their binary and ternary mixtures. The DSC results were used to investigate the liquid-solid phase equilibriu m of n-alkane mixtures, all of which show eutectic behavior. The experiment al liquid-solid phase transformation temperatures were compared with predic tions obtained from available eutectic equilibrium models. The results show the presence of non-idealities in all of the mixtures. (C) 2000 Elsevier S cience B.V. All rights reserved.
