The invention relates to an improved method for purifying an organic solvent for the purpose of absorbing a maleic acid anhydride from a gaseous mixture. The inventive method is characterized by removing the maleic acid anhydride from the solvent, removing a partial flow from the solvent flow, and distilling said partial flow and returning it to the solvent flow. A low- boiling fraction and a high-boiling fraction are removed from the fraction that substantially consists of purified solvent and the fraction that substantially consists of purified solvent is returned to the solvent flow.

Procédé amélioré de purification d'un solvant organique destiné à l'absorption de l'anhydride de l'acide maléique présent dans un mélange gazeux. Ledit procédé consiste à séparer l'anhydride de l'acide maléique du solvant, à prélever une partie du flux de solvant, à distiller ladite partie et à la réintroduire dans le circuit de solvant. Une fraction à point d'ébullition bas et une fraction à point d'ébullition élevé sont prélevées de la fraction constituée pour l'essentiel par le solvant purifié et la fraction constituée pour l'essentiel par le solvant purifié est réintroduite dans le flux de solvant.
