| 摘 要： | 过量焓是溶液的基本热力学性质,近廾年来不少学者对它进行了大量的研究,取得了引人注目的成绩。目前应用较多的为等温稀释型及流动型量热计。尽管后者具有速度快、试剂用量省等优点,但前者结构简单、操作方便和实验精度高,因此得到广泛的应用。传统的等温稀释型量热计的本体为玻璃杜瓦瓶,当活塞上下移动时常常引起破裂,另一方面由于使用汞封,使实验物料受到很大限制。为了克服这些缺点,我们用聚四氟乙烯作为量热计本体,取得满意的效

| Abstract: | A new teflon isothermal dilution calorimeter for measuring excess enthalpies of liquid mixtures is described. The calorimeter has been checked by the excess ent- halpies of binary systems of cyclohexane+hexane, benzene+dichloromethane and acetone+water at 298.15 K, The results indicate that this calorimenter is applicable to both endothermic and exothermic excess enthalpy measurements. |
