Classification of binary mixtures

Synergism of antioxidants was reviewed in the monographs [1-9]. The classification of binary mixtures of inhibitors is based on the mechanisms of action of particular inhibitors [10,11], One of the classification schemes is given in Ref. [11], If one takes into account the... 

In recent years, studies of the phase behavior of salt-water systems have primarily been carried out by Russian investigators (headed by Prof. Vladimir Valyashko) at the Kurnakov Institute in Moscow, particularly for fundamental understanding of the phase behavior of such systems. Valyashko [37,39,42,43], Ravich [38], Urosova and Valyashko [40], and Ravich et al. [41] have given a classification of the existence of two types of salts, depending on whether the critical behavior is observed in saturated solutions. Type 1 does not exhibit critical behavior in saturated solutions. The classic example of Type 1 is the NaCl-water system and has been studied by many authors [36,37,44-47]. The Type 2 systems exhibit critical behaviors in saturated solutions, and therefore have discontinuous solid-liquid-vapor equilibria. Table 1 shows the classification of binary mixtures of salt-water systems. 

The Scott-van Konynenberg classification of binary mixtures helps us organize observed behavior. For example, when we examine an oil reservoir, we know that the number of phases observed will depend on the substances present, as well as on the temperature, pressure, and composition. As material is removed from the reservoir, the state changes, causing the phase behavior to change. Such changes may be, at least qualitatively, anticipated and understandable in terms of the classification of binaries, even though reservoir fluids are not binary mixtures.
