Abstract
A process for producing products from biomass comprising fermenting biomass to produce a first product stream comprising carboxylic acid salts; acidifying at least one of the first product stream and a second product stream to produce a third product stream comprising acids; extracting such acids from the third product stream with a solvent; separating the extracting solvent from the acids to produce the separated extracting solvent and a fourth product stream comprising acids; and processing the fourth product stream to produce a fifth product stream.
