Title (EN) PROCESS FOR RECOVERING CARBOXYLIC ACIDS FROM A FERMENTATION BROTH
(FR) PROCEDE DE RECUPERATION D'ACIDES CARBOXYLIQUES DANS UN BOUILLON DE FERMENTATION
Abstract:
(EN) Carboxylic acids are recovered from a fermentation broth by adjusting the pH of a fermentation broth comprised of a carboxylic acid to at least about 6.0 and then heating the pH-adjusted broth to a temperature sufficient to effect the formation of three immiscible phases, one of which is an oily phase rich in the carboxylic acid.
(FR) Dans cette invention, on récupère les acides carboxyliques dans un bouillon de fermentation en régulant le pH d'un bouillon de fermentation contenant un acide carboxylique jusqu'à au moins 6,0 environ, et en chauffant ensuite le bouillon à pH régulé à une température suffisante pour former trois phases non miscibles, dont l'une est une phase huileuse riche en acide carboxylique.
