Wu jing chemical ethyl acetate production process

2012522Ethyl acetate EtAc is an essential raw material widely used in the chemical industry In this paper, a new reactive distillation RDpervaporation 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
