process of purifying an aqueous solution comprising diethylacetal |
| abstract |
The present invention relates to a process for purifying an aqueous solution comprising ethanol, acetaldehyde and diethyl acetal comprising: - a countercurrent liquid-liquid extraction step a) comprising an extraction section fed at the top by said aqueous solution in admixture with at least a fraction of the refined water / ethanol / acetaldehyde from the re-extraction step (b), and at the bottom by an extraction solvent, which produces at the top an extract and at the bottom a purified filler; - a countercurrent liquid-liquid re-extraction step b) comprising a re-extraction section fed at the top by an acidic aqueous solution of which ph is between 0.5 and 5, and at the bottom by the extract from the step a), which produces at the top an extract and at the bottom a refined water / ethanol / acetaldehyde. |
