Phase equilibria in fluid mixtures

Canada on 14 August 1984) Abstract- Phase diagrams for binary fluid mixtures are reviewed with respect to experimental methods used for their study; the kinds of phase diagram obtained in practice, especially those including one or more of azeotropy, the coexistence of three fluid phases, and the coexistence of two fluid phases ("gas—gas immiscibility") at temperatures above the critical temperature of either pure component; and the extent to which modern theoretical treatments can be used to predict what actually happens at different pressures, temperatures, and compositions
