摘要： 本文采用简单的装置,测定了苯+环己烷(313.25K),苯+正庚烷(308.19K)和环已烷+正庚烷(298.15K)三个体系的蒸汽压-液相组成关系,并由此求得了体系的过量Gibbs自由焓,结果良好。

Abstract: The vapor pressures of benzcne-cyclonexane (313.25K), benzene-n-heptane (308.1119K) and cyclohexane-n-heptane (298.15K) were measured with a tensi-meler. By correlating the vapor pressures with their respective solution compositions, excess Gibbs free energies were calculated by Wilson and Redlich-Kister cquations, in good agreement with published data.
