ABSTRACT:
A method of recovering concentrated sulfuric acid from the product obtained from the acid hydrolysis of a cellulose-containing material such a biomass. The method involves contacting the product with an extraction solvent comprising one or more of the C.sub.4 -C.sub.7 alcohols as the major component to separate the product into a sulfuric acid enriched phase. The sulfuric acid from this enriched phase is then separated and recovered by a further extraction procedure.
