Abrosimov, E. Ivanov, L. Efremova, Yu. Pankratov] The solubilities of gaseous argon in solutions of hexamethylenetetramine (hmta) in H2O and D2O were measured at different concentrations, at five temperatures in the range of 283-318 K, and at a partial gas pressure of 101325 Pa by microvolumetry with an accuracy of ≤0.3%. The standard Setchenov coefficients for argon solutions and the thermodynamic parameters of Ar-hmta pairwise interactions were calculated from the data on the solubility. Interactions between hydrated Ar and hmta molecules are characterized by mutual repulsions. The structural states of water in the hydration sphere of hmta and in the bulk of solution are substantially different. Due to the difference in the mechanisms of hydration of hmta and Ar, the addition of the first component leads to a decrease in the solubility of the second component.
