Abstract
Two sets of benzene saturated vapour pressures, accepted as reference data, are regressed according to the Wagner, Ambrose, Scott–Osborn and modified Cox and Clarke–Glew vapour-pressure equations. In each of these equations the optimum number of regression parameters necessary to fit these data is four. The two equations which have a thermodynamic basis, the Scott–Osborn and Clarke–Glew equations, give the best fit of both data sets. The Clarke–Glew equation is shown to have superior interpolative and extrapolative properties as a vapour-pressure equation.Keywords
