<p><P>PROBLEM TO BE SOLVED: To provide a method for recovering an organic solvent gas from a gas containg an organic solvent by using at least one kind of compound selected from a group consisting of alkylene glycols, alkylene glycolethers and imidazolidinones, and to provide an absorbing liquid suitable for absorbing the organic solvent gas. <P>SOLUTION: [1] The method for recovering an organic solvent gas is to bring the organic solvent gas into contact with the absorbing liquid containing at least one kind of compound selected from a group consisting of alkylene glycols, alkylene glycolethers and imidazolidinones. [2] An absorbing liquid for methylene chloride gas contains at least one kind of compound selected from a group consisting of diethyleneglycol mono-2-ethylhexylether, triethylene glycol monobutylether, diethyleneglycol dibutylether and 1, 3-dimethyl-2-imidazolidinone. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
