Abstract
Improved processes are disclosed for obtaining discrete ethanol and at least one discrete product containing a higher boiling alcohol from an aqueous fermentation broth. In the processes a vaporous, azeotropic mixture is obtained from the fermentation broth through fractionation by distillation and is maintained at a temperature sufficient to effect dehydration without condensation of ethanol and the at least one higher alcohol. The dehydrated mixture of alcohols is further fractionated by distillation to provide a dehydrated, ethanol-rich product and a dehydrated, higher alcohol-rich product.
