Abstract:
The present invention provides a process for recovering fumaric acid formed as a by-product during the production of maleic anhydride so that both fumaric acid and maleic anhydride are obtained. The process of the present invention further eliminates the wasting of MAN that occurs when fumaric acid is incinerated and improves the production of maleic anhydride by eliminating a source of fouling caused by the fumaric acid which leads to down-time in the reaction process to clean out the fumaric acid.
