Solubility of Dimethyl Sulfide in Water

The solubility of dimethyl sulfide in liquid solvents is of considerable interest to the chemical, natural gas, petroleum, food, and pulp and paper industries. There are limited data in the open literature for the solubility of dimethyl sulfide in water at elevated temperatures and pressures. The gaps in the literature data were addressed with new experimental solubility measurements at temperatures in the range (298.15–413.15) K over a wide range of dimethyl sulfide partial pressures. The cubic-plus-association equation of state was used to correlate the new and existing data with a temperature-dependent binary interaction parameter. Henry’s law constants were correlated with temperature over the full temperature range with a Clarke–Glew smoothing equation.
