Beschreibung
Zusammenfassung:	A process and device of coupling separation and purification to produce ethyl tert-butyl ether (ETBE) is provided, wherein ethanol containing 1 wt% to 15 wt% of water, and a mixture containing ETBE and ethanol are fed into the distillation-extraction coupling zone for separation and purification. Said distillation-extraction coupling zone is composed of a distillation column and an extraction column. Said process and device can achieve the cogeneration of ETBE and ethanol, and possesses high commercial values.
