Data on methanol-heptane were not available, but a phase diagram of methanol-cyclohexane is shown below: The x-axis goes from zero methanol (i.e., all cyclohexane) to all methanol (no cyclohexane). The large central area is the two-phase region. Production of polylactic acid aerogels via phase separation and ... The behavior of PDLLA/DMSO/ethanol systems upon cooling from 60 to 25 °C is discussed with the help of a pseudo-binary phase diagram (Fig. 1e). The samples whose composition at 25 °C falls in homogeneous areas of the diagram (L1 or L2 in Fig. 1 e) yield homogeneous liquid solutions which do not form a gel upon storage at 25 °C (state A in ... Binary Vle Phase Diagrams - Feed Composition - Brewiki The first is a "temperature versus x and y" diagram (Txy). The x term represents the liquid composition, usually expressed in terms of mole fraction. The y term represents the vapor composition. The second diagram is a plot of x versus y. These types of diagrams are generated at a constant pressure.
