测定了甲醇、正丙醇、正丁醇和正癸醇在25～85℃温度范围的热压力系数,并为正构醇液体建立了一个热压力系数与密度间的通式.这个通式可用来预测正构醇在各种温度下的内压值.用同形物近似法,本文还获得了正构醇缔合作用的若干重要信息和估计其缔合度的近似方法.%The thermal pressure coefficients of methanol, 1 - propanol, 1 - butanol and 1 - decanol have been measured over the temperature range of 25 ～ 85℃. A generalized relationship between the thermal pressure coefficient and density for normal alcohols was established, which can be used to predict their internal pressure at various temperature. Some valuable information on the association of normal alcohols and method of estimating degree of association were obtained by homomorph approach.
