Henry's law constants for acetone, 2-butanone, 2,3-butanedione, and isobutyraldehyde were investigated using a horizontal flow reactor coupled to molecular beam mass spectrometer. These organics belong class of oxygenated compounds that are increasingly used as industrial solvents chosen better understand evaluate their atmospheric fate. All experiments performed at pressure temperature over the range (275 298) K. The Hx T = 298 K following (in units M·atm-1): (26 ± 6); (2.7 0.3); (57 8); isobutyraldehyde, (0.60 0.10). −d ln Hx/d(1/T) values K): (6400 1600); (12 000 5000); (6700 2400); (4500 2900). uncertainties listed above ±2σ have been calculated propagation errors analysis.
