摘要
醇类在苯及对二甲苯中过量焓预测裘利言，姚惟馨（南京化工学院应用化学系南京２１０００９）关键词醇，芳烃，缔合，过量焓含醇体系的热力学性质研究近来十分活跃。通常文献所报道的醇－芳烃体系中醇的摩尔分数ｘ＿Ａ在０．１～０．９，而对于极稀溶液区有关报道很少。这...
With association equilibrium constants k_A from freezing point depression and Wiehe-Bagley model the excess enthaplies for alcohol and benzene or p-xylene are predicted. The enthalpy of hydrogen bond h_A increases as the carbon numbers n_A of alcohols increase and is a constant after propanol. For the same alcohol h_A is larger in benzene than in p-xylene. The change of molar enthalpies at infinite dilution has similar properdes to h_A There is a linear relationship between ln k_A and In h_A.
