ABSTRACT
Using the steady state method, solubilities of 4-carboxybenzaldehyde and 1,4-benzenedicarboxylic acid in the solvent N-methyl-2-pyrrolidone in the temperature range from (343.2 to 468.2) K and a pressure of 1.6 MPa were determined. The experimental results were correlated by an empirical equation.
