Solubility of hydrogen sulphide, dimethyl ether, methyl chloride and sulphur dioxide in liquids. The prediction of solubility of all gases

The solubilities of hydrogen sulphide, dimethyl ether, methyl chloride, and sulphur dioxide expressed as the mole ratio, X gas , at different temperatures and 1 bar a are given for a number of liquid compounds of types commonly used in operational chemistry. Representative curves showing the variations of X gas , and N gas (mole fraction), with pressure, p gas , are discussed with reference to Henry's law and Raoult's law. With the exception of hydrogen halides and ammonia, the X gas (at a stated t ° and p gas ) for water is much less than for any other liquid reported as examined. The primary factor determining the X gas value at 1 bar is the boiling point of the gas (He to SO 2 ) at 1 bar; the Raoult's law X gas value emerges from this, and places the gases in the same order as the overlapping ranges of real X gas values. The actual X gas value within a particular range for a chosen gas is, for a chosen liquid, seemingly determined by acid‐base functions as defined herein. The prediction of the X gas value is discussed in these terms.
