Beschreibung
Zusammenfassung:	A process of purifying 1,4-butanediol (1,4-BDO) from a fermentation broth including separating solid materials, salts and water, and subjecting the resulting material to a two, three or four column distillation system, that can include a wiped film evaporator to produce a purified 1,4-butanediol product. La présente invention concerne un procédé de purification de 1,4-butanediol (1,4-BDO) à partir d'un bouillon de fermentation. Ledit procédé comprend la séparation de matériaux solides, de sels et d'eau, et la soumission du matériau en résultant à un système de distillation à deux, trois ou quatre colonnes, pouvant inclure un évaporateur à film essuyé, afin de produire un produit de 1,4-butanediol purifié.
