| titleOfInvention | Regeneration method of crude ester |
| abstract | The present invention a) at a temperature T above 100 ° C., the crude ester is mixed with an aqueous base under a pressure p above the vapor pressure of water at temperature T, b) depressurizing the ester-based mixture and evaporating off the water, c) the obtained fluid phase is mixed with water to form a water-in-oil emulsion, d) distilling off water from the emulsion, e) regenerated by filtering esters, A crude ester of an esterification reaction catalyzed by a metal-containing esterification catalyst. By this process, esters having a low acid value are produced, and a residue is produced in an easily filterable form in the solid catalyst residue. |
