Abstract : This paper, which is concerned with the critical evaluation of data on the phase behavior of binary systems, consists of three parts. In the first part the rationale of the evaluation process used is discussed, in the second the behavior of n-pentane, and in the third the behavior of the system methane-n-pentane. The properties of n-pentane considered are the critical constants and the vapor pressures and densities of the saturated coexistent phases as functions of temperature. For the methane-n-pentane system the compositions and densities of the coexisting phases are given as functions of temperature and total pressure. Data for the unique states of the two-component system are also presented. Discussions are given of the reliability of the selected values and of the differences between the selected values and various measured values. (Author)
