Henry's law constants and infinite dilution activity coefficients of propane, propene, butane, 2-methyl-propane, 1-butene, 2-methylpropene, trans-2-butene, cis-2-butene, 1,3-butadiene, dimethyl ether, chloroethane, and 1,1-difluoroethane in 2-propen-1-ol in the temperature range of (250 to 330) K were measured by a gas stripping method. Partial molar excess enthalpies were calculated from the activity coefficients. A rigorous formula for evaluating the Henry's law constants from the gas stripping measurements was used for the data reduction of these highly volatile mixtures. The estimated uncertainties are about 2 % for the Henry's law constants and 3 % for the infinite dilution activity coefficients. In the evaluation of the infinite dilution activity coefficients, the nonideality (fugacity coefficient) of the solute cannot be neglected, especially at higher temperatures. The estimated uncertainty of the infinite dilution activity coefficients includes 1 % for the nonideality. In general, the Henry's law constants followed the order of increasing Henry's law constant with decreases in the normal boiling point temperature of the liquefied gas except for 1,3-butadiene, and the partial molar excess enthalpies of gases followed the order of increasing partial molar excess enthalpy with decreases of the polarity of the gases.
