| titleOfInvention | Solvent for Recovery of Maleic Anhydride from a Gas Stream |
| abstract | A process is described for producing crude maleic anhydride from a reactor effluent stream containing maleic anhydride. The reactor effluent stream is contacted with a solvent having a normal boiling point between about 250° C. and about 350° C., solubility of fumaric acid at least about 0.06 wt % at 60° C., solubility of maleic anhydride at least about 10 wt % at 60° C., solubility in water no higher than about 100 mg/L, density different from the density of water by at least about 0.020 g/mL, and water soluble hydrolysis products with molecular weight no higher than the molecular weight of pentanol. The solvent may be non-cyclic, non-aromatic, linear, and/or branched, and may have the general structure R 1 COOR 2 COOR 3 , wherein R 1 and R 3 are each linear or branched C 3 to C 5 groups and R 2 is a linear or branched C 3 to C 8 group. |
