Open full text 3 citations

Abstract

Acentric factor estimation from the corresponding states principle was conducted. The reported values, or analytical expressions, of the functions f(0), f(1) and f(2) are presented. The tabulated values of f(0), f(1) and f(2) by the Brandani relation of the Wagner type of vapor pressure equation are correlated. The estimation procedures are tested on 44 nonpolar substances. The Ambrose and Walton expressions have the best predictive characteristics.
