ABSTRACT

Henry s law constants and infinite dilution activity coefficients of propane, propene, butane, 2-methylpropane, 1-butene, 2-methylpropene, trans-2-butene, cis-2-butene, 1,3-butadiene, dimethyl ether, chloroethane, and 1,1-difluoroethane in 2-methyl-3-buten-2-ol and 3-methyl-3-buten-1-ol in the temperature range of (250 to 330) K were measured by a gas stripping method, and partial molar excess enthalpies were calculated from the activity coefficients. The estimated uncertainties are about 2 % for the Henry s law constants and 3 % for the infinite dilution activity coefficients. 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 except for chloroethane and 1,1-difluoroethane.
