<p><P>PROBLEM TO BE SOLVED: To provide a method for dehydrating a water-containing organic compound, by which capability of dehydrating a water-containing organic compound can be improved without increasing the size of an apparatus. <P>SOLUTION: The method for dehydrating a water-containing organic compound comprises introducing a water-containing organic compound into a distillation column and then removing by an adsorption means the highly concentrated organic compound from the concentrated water-containing organic compound steam that is obtained from the distillation column top, wherein a membrane separation means is provided between the distillation column and the adsorption means, so that the reflux rate of the distillation column and/or the membrane area in the membrane separation means is variable and the water-containing organic compound steam concentrated at the distillation column top is supplied at a predetermined proportion to the membrane separation means and then to the adsorption means, so that the highly concentrated organic compound can be obtained in the form of steam. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
