Abstract
L'invention concerne l'industrie chimique. Procédé de récupération d'anhydride maléique dans une composition gazeuse contenant de l'anhydride maléique et de l'eau, par condensation de la composition à une température d'environ 20 à 50 degrés C, sous une pression réduite inférieure à 200 mm de Hg. Le procédé s'applique à la purification de l'anhydride maléique brut obtenu par oxydation en phase vapeur d'hydrocarbures.The invention relates to the chemical industry. Process for recovering maleic anhydride in a gaseous composition containing maleic anhydride and water, by condensing the composition at a temperature of about 20 to 50 degrees C, under a reduced pressure of less than 200 mm Hg The process applies to the purification of crude maleic anhydride obtained by vapor phase oxidation of hydrocarbons.
