Liquid Liquid Phase Separation

The phase diagram t-butanol/water is studied in the temperature range between 200 and 450 K at pressures up to 200 MPa. No liquid/liquid phase separation is observed in this range. The solid/liquid phase diagram reveals the presence of a stable t-butanol/dihydrate at all pressures. At the t-butanol rich side of the diagram solid mixtures with compositions t-butanol/water ~ 5 :1 and ~ 6 : 1 are observed.
