SOLUBILITY OF O-2 IN 2-PROPANONE, 2-BUTANONE, 2-PENTANONE, AND 2-HEXANONE

Experimental data for the solubility of O2 In CH3COCH3, CH3COC2H5, CH3COC3H7, and CH3COC4H9 within the temperature range 298-344 K are reported. For T = 298.2 K the following values for Henry's constant were measured (HO(P bar/mole fraction): ketone C3, 1190; C4, 986; C5, 904; C6, 855. The data can be well correlated by using the semlemplrlcal approach of Cysewskl and Prausnltz. The prediction of Henry's constant of O2 for higher ketones by the regular solution equation is tested and found applicable. A rapid technique for performing oxygen solubility measurements on a working sample is described and tested. © 1979, American Chemical Society. All rights reserved.
