Název v původním jazyce

Separation of methyl acetate methanol azeotropic mixture using ionic liquid entrainers

Popis výsledku v původním jazyce

Two ionic liquids (ILs), namely 1-butyl-1-methylpyrrolidinium dicyanamide [BMPYR][DCA] and 1-ethyl-3-methylimidazolium thiocyanate [EMIM][SCN], were studied as agents for the separation of the methyl acetate + methanol azeotropic mixture by extractive distillation. Isothermal vapor-liquid equilibria of the ternary systems with the ILs and all the constituting binary subsystems were measured by headspace gas chromatography (HSGC) to examine the effect of the IL additives on the separation factor. Two HSGC methods were combined to this end: one employing a commercial headspace autosampler and the other employing our own setup with external equilibrium cell and forced circulation of the vapor phase through the GC sampling loop. The HSGC methodology developed herein presents distinct advantages compared to conventional dynamic measurements using recirculation stills. The measurements were conducted at 327.31 K, a temperature close to the normal boiling point of the methyl acetate + methano
