Abstract
The invention relates to a process for the production of alcohols from biomass that comprises a stage in which at least one aqueous internal flow that comprises at least one alcohol that has n carbon atoms, with n between 2 and 5, is recycled, provided that when the alcohol comprises 2 carbon atoms, it is mixed with at least one other alcohol in such a way as to recover a vapor phase effluent that contains alcohols exiting from said pretreatment reactor.
