DISTRIBUTION OF SOLUTES BETWEEN COEXISTING STEAM AND WATER

For a thorough description of aqueous systems with coexisting liquid-v apor phases, it is necessary to have a means of describing the concent ration of solutes in the two-fluid phases over a wide temperature rang e. A general procedure is presented which allows the description of th e distribution ratio of solutes at infinite dilution (K(D)) between wa ter and steam over all the range of coexistence of the two-fluid phase s. The procedure has been employed for many different solutes, e.g., n onreactive gases, reactive gases, nonionic, and ionic solutes. For the gaseous solutes a formulation is given which allows the calculation o f K(D) over the complete temperature range with good precision.
