Measurement through a Gas Stripping Technique of Henry's Law Constants and Infinite Dilution Activity Coefficients of Propyl Mercaptan, Butyl Mercaptan, and Dimethyl Sulfide in Methyldiethanolamine (1) + Water (2) with w1 = 0.25 and 0.35

ABSTRACT
Reported herein are determinations of Henry s constants and limiting activity coefficients obtained by an inert gas stripping method for propyl mercaptan, butyl mercaptan, and dimethyl sulfide in the temperature range (293 to 343) K at atmospheric pressure in water and in (0.25 and 0.35) wt % methyldiethanolamine (MDEA) aqueous solutions. They are supplemented by additional data from the literature at a mass fraction of 0 and 0.5 MDEA. The influence of the solvent is discussed considering the heat of absorption for the different amine concentrations.
