Vapor–liquid equilibrium in the system of propylene oxide synthesis products

Vapor–liquid equilibrium data calculated for the systems formed by propylene oxide synthesis products have been compared to the same data available from the literature. Using the NRTL and UNIQUAC models, the vapor–liquid equilibrium data available from the literature for the systems have been optimized, the model parameters and their errors have been estimated, and the corresponding diagrams have been calculated and mapped. A process flowsheet for propylene oxide isolation from the reaction mixture is suggested.
