Entrainers selection and vapour-liquid equilibrium measurements for isopropyl acetate with propyl propionate, butyl propionate, and butyl butyrate at 101.3 kPa

Extractive distillation with propyl propionate, butyl propionate and butyl butyrate as extractive solvents is adopted to separate the binary azeotrope isopropyl alcohol + isopropyl acetate. Through the relative volatility and x-y diagrams, the influence of the three entrainers on the vapour-liquid equilibrium (VLE) behaviour is also explored. The isobaric VLE data for the binary systems of isopropyl acetate + propyl propionate/ butyl...
