Partition coefficients of phenol, salicylic acid, and several environmentally sensitive chloro- and nitrophenols in water-supercritical CO2 system have been measured using direct co-current extraction of aqueous solutions of the individual solutes with CO2. The partitioning data on the nitrophenols and salicylic acid appear to be reported for the first time. The pros and cons of the particular method of measurement have been outlined in the poster.
