ABSTRACT OF THE DISCLOSURE A lower alcohol compound is separated from a mixture of a lower alcohol compound and an ether compound by a pervaporation method comprising the steps of: bringing a feed comprising an ether compound and a lower alcohol compound into direct contact with a feed face of a specific asymmetric separating membrane comprising an aromatic imide polymer which has 70 to 100 molar% of recurring units selected from those of the formulae (I) and (II) Image (I) and Image (II) wherein R = divalent aromatic group having two or more benzene rings and X = -S-, -SO2-, -CO-, -O-, -C(CH3)2-, -CH2- and -C(CF3)2-; exposing a delivery face Opposite to the feed face of the membrane to a pressure-reduced atmosphere to cause the lower alcohol compound to selectively permeate through the membrane and to be then vaporized at the delivery face side, and collecting the lower alcohol compound at the delivery face side of the membrane.
