## Abstract A new correlation of second virial coefficients of both polar and nonpolar systems is presented. It uses the PitzerβCurl correlation for nonpolar compounds, but in a modified form. The second virial coefficient of nonhydrogen bonding compounds (ketones, acetaldehyde, acetonitrile, ether

A new correlation has been developed for calculation of second virial coefficients of polar compounds. The new procedure uses superimposition of the square well potential function and a term accounting for the dipoltiipole interaction. Parameters for this new correlation have been determined for 13
## Based on a selected p, f~ T data set of oxygen for the range from low to moderate densities an equation of state for oxygen vapour has been established From this evaluation, new values for the second and third virial coefficients were derived In addition, correlation equations for the temperatu
