METHOD AND EQUIPMENT FOR REMOVING IMPURITIES FROM NITRATED AROMATIC COMPOUNDS |
| 摘要 |
<p>The present invention relates to a method for extracting hydrophilic mineral and organic acids from aromatic compounds, in particular nitroaromatic compounds, preferably crude mononitrobenzene (MNB), by purifying and refining these compounds. This invention further relates to a device or equipment that comprises an assembly of static mixers arranged in series and/or in parallel, followed by a liquid-liquid separator and then by a coalescer, and also to the recycling of a fraction of the acid water separated in the coalescer.</p> |
