Title:
METHOD FOR PRODUCING CARBON FILM, CARBON FILM AND SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2011/004660
Kind Code:
A1
Abstract:
Disclosed are a method for producing a carbon film which has a separation performance equivalent to carbon films of the prior art and an improved permeation performance, a carbon film and a separator for a liquid mixture. The aforesaid method for producing a carbon film comprises thermally decomposing a carbon-containing layer, which is a precursor, in an oxygen inert atmosphere and then thermally oxidizing the thus obtained carbon film while flowing a gas mixture containing an oxidizing gas. It is preferred that the carbon film is thermally oxidized with controlling the ratio of the flow rate of the gas mixture to the area of the carbon film to 0.5 cm/min or higher so as to control the relationship between the temperature of the gas mixture and the flow time, which is represented by (temperature oC)2 × time(h)/10000, to 9 to 32 inclusive. Thus, a carbon film, by which alcohols having 2 or less carbon atoms are selectively separated from a liquid mixture comprising the alcohols having 2 or less carbon atoms with organic compounds having 6 to 9 carbon atoms, is obtained.
