During the first half of Phase I of this research program, the following elements of research were performed: (1) the collection and processing of data for pure components which is 80 percent complete as to substance, (2) the evaluation of the generalized Modified Benedict-Webb-Rubin (MBWR) equation of state for halogenated hydrocarbon saturated thermodynamic properties, (3) the determination of the pure component parameters of the MBWR for four polar fluids, and (4) the investigation of modifications of the MBWR for improved prediction of properties of polar fluids. A primary conclusion of the Phase I work is that the MBWR will predict properties for polar fluids with small to moderate dipole moments (less than 1.6 Debyes) but needs modification for fluids with larger moments.
