摘要：
Specific retention volumes were measured in the range 25-75°C for benzene + squalane, benzene + triethylene glycol and n-hexane + squalane and in the range 15-55°C for benzene + tetraethylene glycol dimethyl ether, each in steps of 5°C. Values for the solution thermodynamic properties and their errors were obtained by fitting the experimental data to equations with two or more constant by using the method of Clarke and Glew. The best thermodynamic results were obtained by means of the three-constant equation; adding a fourth constant did not improve the adjustment. However, when the objective is interpolation, the results obtained with the classical, two-constant equation, are of adequate accuracy. © 1990.
