| titleOfInvention | Method for recovering organic acids from the production of cellulose esters |
| abstract | (57) Abstract: A method for recovering an organic acid generated from the production of cellulose ester is provided. SOLUTION: A step of removing an acid from a weak acid stream containing an organic acid and water, solvent-extracting the weak acid stream, thereby forming an overhead stream and a raffinate stream, the raffinate stream comprising a solvent, water and an alcohol. A step in which the alcohol is produced by a recovery method by hydrolysis of the solvent after the solvent extraction step, the raffinate stream is separated into an overhead stream and a bottom stream, the overhead stream comprising water, alcohol and A step of containing a solvent, a step of adding an excess organic acid to the overhead stream to form a feed stream, and a step of catalyzing the feed stream by an ion exchange resin, thereby esterifying a part of the alcohol into the solvent And the step of recycling the last-mentioned solvent to the recovery method. |
