Abstract: A C1-4 alcohol is separated from a mixture of a C1-4 alcohol and an ether by a pervaporation method comprising the steps of: bringing a feed comprising an ether compound and a C1-4 alcohol compound into direct contact with a feed face of a specific asymmetric separating membrane comprising an aromatic imide polymer which preferably has 70 to 100 molar% of recurring units selected from those of the formulae (I) and (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 C1-4 alcohol compound to selectively permeate through the membrane and to be then vaporized at the delivery face side, and collecting the C1-4 alcohol compound at the delivery face side of the membrane.

Abstract: PURPOSE:To permeate a lower alcohol selectively and separate it from vapor of a mixture containing the lower alcohol such as ethanol and an organic compound by using a gas separating membrane of a heat-resistant polymer having a specific gas diffusible function. CONSTITUTION:A gas separation membrane to be used is a gas separation membrane of a heat-resistant polymer having 2.0-400 separation degree at 25 deg.C [the ratio of diffusing speed of helium gas to that of sulfur hexafluoride gas (PHe/PSF6)] and permeation speed of methanol at 80 deg.C (PCH3OH) of at least 1.0X10 cm /cm .sec.cmHg. Vapor of a mixture containing 1-2C lower alcohol (including methanol, etc.) and an organic compound is brought into contact with one side (a supplying side) of the gas separation membrane at 60 deg.C and the lower alcohol is selectively permeated to the other side (a permeating side) of the gas separation membrane, so that a lower alcohol such as methanol, etc., is separated.

Abstract: PURPOSE:To effectively separate lower alcohol as vapor from a liq. mixture of the alcohol with an org. ether by bringing the mixture into direct contact with one side of a heat resistant asymmetric separating membrane of an arom. polyamide. CONSTITUTION:A liq. org. compd. mixture of 1-4C lower alcohol with an org. ether is fed into a separating membrane module and brought into direct contact with an asymmetric separating membrane of an arom. polyamide built in the module. The permeation side of the membrane is kept under reduced pressure as required and the lower alcohol is allowed to selectively permeate the membrane, vaporized and separated. The highly concd. org. ether is finally taken out and recovered from the feed side of the membrane and vapor contg. a highly concd. lower alcohol from the permeation side. By this method, the lower alcohol is industrially and stably separated and recovered over a long time.
