Abstract

L'INVENTION CONCERNE L'EXTRACTION DE L'ACIDE METHACRYLIQUE OBTENU PAR OXYDATION CATALYTIQUE DE LA METHACROLEINE. L'EFFLUENT 20 DE L'OXYDATION EST REFROIDI 22, 26 ET L'EFFLUENT CONDENSE 36 EST EXTRAIT A L'AIDE D'UN MELANGE D'UNE CETONE ET D'UN SOLVANT AROMATIQUE (METHYL-N-PROPYL-CETONETOLUENE) AFIN DE REJETER L'EAU ET LES IMPURETES 46. LA DISTILLATION 40 DU SOLVANT RICHE 39 DONNE L'ACIDE METHACRYLIQUE BRUT AM CONTENANT DE L'ACIDE ACETIQUE AA. L'EAU ET LE SOLVANT OBTENUS EN TETE DE COLONNE 40 SONT TRAITES 48, 52 POUR RECUPERER LA METHACROLEINE M ET LE SOLVANT 50. L'ACIDE METHACRYLIQUE EST UN INTERMEDIAIRE DE SYNTHESE.THE INVENTION CONCERNS THE EXTRACTION OF METHACRYLIC ACID OBTAINED BY CATALYTIC OXIDATION OF METHACROLEIN. THE EFFLUENT 20 OF THE OXIDATION IS COOLED 22, 26 AND THE EFFLUENT CONDENSE 36 IS EXTRACTED USING A MIXTURE OF A KETONE AND AN AROMATIC SOLVENT (METHYL-N-PROPYL-KETONETOLUENE) IN ORDER TO DISCARD WATER AND IMPURITIES 46. DISTILLATION 40 OF RICH SOLVENT 39 GIVES CRUDE METHACRYLIC ACID AM CONTAINING ACETIC ACID AA. THE WATER AND THE SOLVENT OBTAINED AT THE TOP OF COLUMN 40 ARE TREATED 48, 52 TO RECOVER THE METHACROLEIN M AND THE SOLVENT 50. METHACRYLIC ACID IS A SYNTHESIS INTERMEDIATE.
