Abstract

Vapor phase concentrations of acetone, acetaldehyde and acetonitrile over their aqueous solutions were measured to determine Henry's law partition coefficients for these compounds in the temperature range 5-40-degrees-C. The results are for acetone: ln(H1/atm) = -(5286 +/- 100)T+ (18.4 +/-0.3); acetaldehyde: ln(H1/atm) = - (5671 +/- 22)/T + (20.4+/- 0.1); and acetonitrile: ln(H1/atm) = -(4106 +/- 101)/ + (13.8 +/-0.3). Artificial seawater of 3.5% salinity in place of deionized water raises H1 by about 15%. A similar technique has been used to measurethe equilibrium constants for the addition compounds of acetone and acetaldehyde with bisulfite in aqueous solution. The results are ln(K1/M-1) = (4972 +/-318)/T - (11.2 +/-1.1) and ln(K1/M-1) = (6240 +/- 427)/ T - (8.1 +/- 1.3), respectively. The results are compared and partlycombined with other data in the literature to provide an average representation.
