ABSTRACT:
There is disclosed, in one aspect, a continuous process for producing n-butanol. This process comprises (a) continuously contacting at least one carbohydrate-containing substrate, such as blackstrap molasses, with an n-butanol producing culture, such as Clostridium acetobutylicum (Weizmann), in water to effect the fermentation of the substrate and form a product mixture comprising n-butanol, (b) continuously extracting the product mixture from the substrate, culture, and water by forming a solution of the product mixture with an extraction solvent, such as monofluorotrichloromethane, (c) continuously separating the extraction solvent from the product mixture by vaporizing substantially all of the solvent without substantial vaporization of the product mixture, and (d) continuously condensing the vaporized solvent for reuse as an extraction solvent in step b. In another aspect, there is disclosed an apparatus for conducting such a process.
