摘要：

Due to the azeotrope between ethanol and isopropyl acetate,separatingthem and meeting the separation requirements is challenging. In thisstudy, ethylene glycol (EG), dimethyl sulfoxide (DMSO), and 1-butyl-3-methyl-imidazoleacetate ([BMIM]-[OAC]) were selected as entrainers, and the vapor-liquidequilibrium data of ethanol-isopropyl acetate, ethanol + isopropylacetate + EG, ethanol + isopropyl acetate + DMSO, and ethanol-isopropylacetate + [BMIM]-[OAC] were measured at atmospheric pressure. The thermodynamicNRTL model was able to fit these experimental results. It showed thatthe model could correctly describe the influence of these entrainerson this azeotropic system. According to the VLE data, three entrainerscaused different effects on the relative volatility of ethanol-isopropylacetate. The azeotropic point would be completely eliminated, whilethe mole fraction of [BMIM]-[OAC] added is 0.1, which performs betterthan EG and DMSO.
