ABSTRACT

Using a flow-type apparatus, the solubilities of p-aminobenzenesulfonamide in supercritical carbon dioxide were determined at three different temperatures (308.15, 318.15, and 328.15) K and in the pressure range from (11.0 to 21.0) MPa. The effect of acetone cosolvent on the solubility of p-aminobenzenesulfonamide was studied at the mole percents of 3.0 % and 6.0 %. The experimental data in supercritical carbon dioxide without and with cosolvent were satisfactorily correlated with the Chrastil equation and the modified Chrastil equation.
