The method in which tritium oxide acts as a tracer in the determination of water solubility in hydrocarbons has been used for the measurement of the solubility of water in a number of paraffinic, olefinic, and diolefinic hydrocarbons. The effect of temperature, pressure, size of hydrocarbon molecule, and the constitutive factors have been studied. Solubilities were determined in the temperature range from 5° to 30°C at pressures from 1 to 6 atmospheres.
This simplified approach to predicting phase equilibria cuts a clean path through the usual tangle of data and calculations ^Representation of phase equilibria with activity coefficients immediately presents three important problems: effects of vapor phase imperfections on phase equilibria and the influences of liquid composition and temperature on the activity coefficients. In dealing
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
