In the present work, effect of the attraction terms of four recently modified Peng-Robinson (MPR) equations of state on the prediction of solubility of caffeine, cholesterol, uracil and erythromycin was studied. The attraction terms of two of these equations are linear relative to the acentric factor and for the other two are exponential. It is found that the later show less deviation. Also interaction parameters for the studied systems are obtained and the percentage of average absolute relative deviation (%AARD) in each calculation is displayed. (C) 2008 Mohammad Reza Bozorgmehr.
