A Modified General Corresponding States Equation for Polar Liquid Mixtures
Great attention has been paid to the use of corresponding states principle for predicting the properties of fluids.The equation proposed by Pitzer et al.[l], introducing ascentric factor (ω) as a third parameter, is mostly well known. As (ω) accounts mainly for the shape and size of a molecule, so Pitzer’s equation gives relatively large deviations for polar fluids with dipole moments. In view of this problem, several corresponding states equation with a fourth parameter have been developed. Among these, the one with reduced dipole moment (µR,) proposed by O’Connell and Prausnitz  has some theoretical ground. But, because µR enters as a logarithm term in their equation for calculating the second virial coefficent, they include a factor of 10 in5 in µR,thus their equation has limitations. Recently, Wang Rengyoan has made rather systematic review of the development of corresponding states principle.
