ABSTRACT:
An improved process is provided for concentrating organic compounds from dilute aqueous solutions such as fermentation liquors. Conventional distillation of the compounds to remove the bulk of the water is eliminated by selective adsorption on adsorbent carbon. The compounds are eluted from the carbon with the vapors of a volatile solvent and then the volatile solvent is evaporated from the eluate to give a concentrated aqueous solution containing at least 30% by weight of the organic compounds.
