| titleOfInvention | Purification of organic solvents to absorb maleic anhydride. |
| abstract | The maleic anhydride is separated from the solvent, a partial stream is taken from the solvent stream, this partial stream is distilled and returned to the solvent circuit, an organic solvent for absorbing maleic anhydride from the gaseous mixture. Improved purification methods have been proposed, in which the low-boiling fraction and the high-boiling fraction are separated from a fraction consisting essentially of the purified solvent and a fraction consisting essentially of the purified solvent Is fed back into the solvent stream. |
