| titleOfInvention | PROCEDURE FOR PURIFICATION OF AN ORGANIC SOLVENT FOR THE ABSORPTION OF MELEIC ACID ANHYDRIDE. |
| abstract | Procedure for the purification of an organic solvent intended for the absorption of maleic acid anhydride from a mixture in the gaseous state, the anhydride being separated from the maleic acid from the solvent, a partial stream is removed from the solvent stream, this partial stream is Distilled and recycled to the solvent circuit, characterized in that they are separated from the fraction, which is essentially constituted by the purified solvent, a fraction of the low boiling products and a fraction of the high boiling products and the fraction, which is essentially constituted by the purified solvent, is recycled back to the solvent stream. |
