The Pressure Dependence of the Phase Diagram t-Butanol/Water

Abstract

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. © 1985, Walter de Gruyter. All rights reserved.
