Ethyl acetate (EtAc) is an essential raw material widely used in the chemical industry. In this paper, a new reactive distillation (RD)–pervaporation (PV) coupled process for ethyl acetate (EtAc) production is proposed, in which the PV membrane is located in the bottom stream in order to selectively remove the water from the reboiler and recycle the acetic acid (HAc) into the feed.
