Alkane-solvent, phase diagram

Figure 37c shows the alkane—solvent phase diagram calculated by equating A = BE (top curve equilibrium liquidus) and A = BF (bottom curve metastable liquidus). Imagining that crystal growth rate G is plotted on the x-axis, and bearing in mind that on either of the liquidus lines G is zero, the c and T dependencies of G in Figure 37a and b can be... 

Returning now to the phase diagram of polymer solutions, we emphasize also that much more complicated phenomena than envisaged in Figure 2a can occur. For example, considering the solution of short alkane chains (eg hexadecane) in carbondioxide, one encounters a competition between gas-liquid transitions of both polymer (Cie H34) and solvent (CO2) and liquid-liquid phase separation (99,100). Thus the phase diagram not only contains (in the space of three variables p,T, and ) various lines of critical points, but special points such as critical end points, triple points, and tricritical points may also occur. Each system then... 

Microemulsions are widely used in apphcations because they are transparent, isotropic, stable low-viscosity mixtures [32]. Kahlweit and Strey performed several investigations drawing a different type of phase diagram (called fish phase diagram) [32-36]. Usually, the polar phase is water, while the nonpolar phase is a n-alkane solvent. Recently, the scientific interest has increased many folds for employing RTILs... 

Figure 11 Phase diagrams of dodecyldimethylphosphine oxide in a family of homologous alkan-ols. That part of the phosphine oxide-water phase diagram linked to th dry phosphine oxide border is also shown. The form of these diagrams differs substantially from that of most surfactant—solvent systems (Fig. 10) in that the melting-point-depression region is expanded and the plateau region is small or nonexistent. (From Ref. 96.)...

Fig. 7 SRK master diagram for phase behavior at ky = 0. X, A, n are the computed type for II, III, and IV regions. Computations are based on n-alkanes with N2, CH4, C2H6, CO2, CH3OH, and H2O as solvents.
