2 Mercaptan in Methyldiethanolamine (1) + Water (2) with w 1 = 3 0.25 and 0.50 at temperature of 298 to 348K using Inert Gas dilution in a mass fraction of 25%, and 50% of methyldiethanolamine (MDEA) aqueous 19 solution within the temperature range of 298-348 K at atmospheric pressure, were measured. 20 An inert gas stripping method was used to perform all the measurements. The new values of 21 Henry's Law Constant and the activity coefficients in infinite dilution correlation with solute 22 molecular size were explained. The influence of the solvent is discussed taking into 23
