摘要
测制了正丁醇—正十六烷的固液平衡相图，属简单低共熔混合物类相图．计算出体系在２９８．１５Ｋ的摩尔过量吉布斯自由能ＧＥｍ，其最大值为１７８３Ｊ·ｍｏｌ－１．用Ｗｉｅｈｅ－Ｂａｇｌｅｙ（ＷＢ）模型进行处理，得到正丁醇的自缔合常数ＫＡ，２９８．
Melting temperatures have been measured and the solid liquid phase diagram was constructed for n butanol+n hexadecane. It is a simple eutectic system. Excess molar Gibbs free energies at 298.15 K were calculated. The largest value of G E m is 1 783 J·mol -1 . The data was treated with Wiehe Bagley association model combining with a Hildebrand Scatchard term. The self association constants K As have been calculated, and the value of K A at 298.15 K for n butanol in n hexadecane is 118.
