Abstract: A new generalized correlation tor the estimation of heat capacities of liquid organic compounds has been developed. It is applicable to many types ot organic compounds including the strong polar and associated compounds and to the temperature range from the reduced melting point Tm, to the reduced temperature of 0.95. The heat capacities of 103 compounds, have been calculated with this method and compound with data of 1567 points, and an absolute average deviation of 3% has been obtained for all types of compounds except acids for which it has been shown to be 5%. The results are better than those of published methods.

摘要： 本文通过热力学推导和经验校正,提出了一个新的推算有机化合物液体等压热容的关联式.该方法适用于多种类别的化合物,包括强极性的和缔合性化合物.计算的温度范围可以从对比熔点到0.95的对比温度.用该方法计算了103个化合物的等压热容,计算结果与实验数据比较吻合,其精度优于已有的文献方法.
