The quality and applicability of the above approach may be evaluated by applying the Eq. (18) to five typical fluids: argon, methane, methanol, benzene and water, which cover spherical, nonpolar and polar molecules. There is a lot of sources to get the compressibility factor (Z factor) data of pure substance. Among the famous ones, National Institute of Standards and Technology (NIST) provides open data that is based on the most accurate pure fluid and has been selected on the sound scientific

This paper developed a novel approach to determine averaged binary potential field (ABPF) from compressibility factor. After the concepts of intermolecular potential field and idealized symmetric fluid were introduced, relevant thermodynamical analytical expressions for the fluid were derived. Especially, a new equation relating the compressibility factor with the ABPF was obtained. And then, the obtained equation was applied to five typical fluids: argon, methane, methanol, benzene and water, which covers spherical, nonpolar and polar molecules. It was found that all the ABPFs of the five flu...
