Abstract : This paper is the first in a series of reports on the critical evaluation of vapor-liquid equilibrium, heat of mixing, and volume change of mixing data for binary liquid mixtures of nonelectrolytes. The specific evaluation procedures for each property will be covered in subsequent articles. This paper describes the general procedures used to support the mixture evaluation work. The areas covered include the procedures used to cover the primary and secondary literature, the computer program libraries developed for pure compound and mixture data processing, the procedures used to evaluate and correlate the pure compound property data for use by the mixture programs, and the efforts made to make the best equation of state available to the vapor-liquid equilibrium data reduction programs. Improvements are suggested for the presentation of mixture data in the literature. (Author)
