| titleOfInvention | Process for the simultaneous production of maleic anhydride and its hydrogenated derivatives |
| abstract | The present invention relates to the co-production of C 4 compounds selected from maleic anhydride with butane-1,4-diol, γ-butyrolactone and tetrahydrofuran, by partial oxidation of a hydrocarbon feed selected from C 4 hydrocarbons and benzene. A gaseous reaction discharge stream comprising maleic anhydride, water, unconverted hydrocarbon feed, and carbon oxides is prepared to provide maleic anhydride. Some of the maleic anhydride present in the gaseous reaction discharge stream is condensed to form a crude maleic anhydride stream and a residual gaseous stream containing the remaining amount of maleic anhydride is left. It also absorbs maleic anhydride in an organic solvent, water or aqueous solution from the residual gaseous stream. The maleic anhydride is then recovered from the charged liquid absorption medium. The at least one C 4 compound is one produced by hydrogenation of a C 4+ feed consisting of maleic anhydride, maleic acid, dialkyl maleate, a mixture of two or more thereof. Be used in the method the material of the crude maleic anhydride with C 4+ hydrogenation feed or used to prepare the C 4+ hydrogenation feedstock. |
