Abstract Solubilities of maleic acid and phthalic acid in binary system in supercritical carbondioxide have been measured as a function of equilibration time acid content in equilibriumcell pressureand temperature Solubilities of maleic acid in three isotherms 45 60 and 75 C and pressure range of 70 300 bar were 1 30 2 41 x 10 5 3 13 8 65 x 10 5 24 81 59 17 x 10 5 respectively Solubilities of phthalic acid in three isotherms 45 60 and 75 c and pressure range of 80 300 bar were 0 33 2 02 x 10 5 0 50 2 34 x 10 1 80 58 08 x 10 5 respectively The Solubilities are correlated with Chrastil equation andassociation number for maleic acid and phthalic acid were found as 1 53 and 2 13 respectively Solubility of maleic acid was found greater than phthalic acid that is related to lowermolecular weight and melting point and greater vapor pressure 1lff 1 J
