Abstract
Technical fermentations, such as the acetone‐butanol fermentation and the 2: 3‐butylene glycol fermentation, yield products in the form of very dilute aqueous solutions. The volatile products may be isolated by adsorption on active carbon. In the case of 2 : 3‐butylene glycol the desorption has to be effected by solvent extraction, for which acetone is most suitable. In the case of acetone‐butanol, it is not only possible to adsorb the solvent mixture, as produced by fermentation, but also to isolate the two components separately by selective adsorption. The adsorbent bed can be re‐used, without decrease in its adsorptive capacity.
