(FR) PROCÉDÉ DE PURIFICATION D'ACIDE ACÉTIQUE ET D'ACIDE ACRYLIQUE
Abstract: front page image
(EN)The present disclosure relates to a method for purifying an acid, wherein the method comprises: a) producing a crude product mixture by a partial oxidation reaction, wherein the crude product mixture comprises acrylic acid and acetic acid; b) purifying the crude product mixture by distillation using a high-boiling solvent to purify the acrylic acid; and c) purifying the crude product mixture by distillation using a low-boiling solvent to purify the acetic acid.
(FR)La présente invention concerne un procédé de purification d'un acide, le procédé comprenant : a) la production d'un mélange de produit brut par une réaction d'oxydation partielle, le mélange de produit brut comprenant un acide acrylique et un acide acétique; b) la purification du mélange de produit brut par distillation au moyen d'un solvant à point d'ébullition élevé pour purifier l'acide acrylique; et c) la purification du mélange de produit brut par distillation au moyen d'un solvant à point d'ébullition bas pour purifier l'acide acétique.
