Measurement and correlation of vapor-liquid equilibria of ethanol-dimethyl carbonate-chlorobenzene
摘要
Abstract
Vapor-liquid equilibria of ethanol-dimethyl carbonate (DMC),DMC-chlorobenzene and ethanol-DMCchlorobenzene in a solvent ratio(volume ratio) of 1 ∶ 1 were measured at 101.3 kPa,and Herington area integration method was used to check the thermodynamic consistency.Furthermore,the experimental data were correlated by means of Wilson equation,in which the binary interaction parameters were also obtained.It shows that chlorobenzene can enlarge the relative volatility of ethanol and DMC,and the azeotropic point disappears when the mole fraction of chlorobenzene reaches 0.35,which demonstrates the feasibility of separating ethanol-DMC using extractive distillation with chlorobenzene as solvent.关键词
