Infrared spectra of benzoic acid in CO2-ethanol and CO2-dimethyl sulfoxide(DMSO) mixed supercritical fluids have been determined at 35.0℃ and 12.6MPa. It was observed that benzoic acid exists in both forms of monomer and dimer in pure supercritical CO2. Benzoic acid begin to form hydrogen-bonded complexes with ethanol and DMSO even their concentrations are very low and the concentration of the monomer of benzoic acid decreases with increasing of ethanol concentration, provided that the total concentration of the acid is fixed.
