摘要

Process for the separation of volatile organic acids and furfural from liquids containing them, characterized in that in the liquid-liquid extraction, an organic solvent with a boiling point higher than that of furfural is used and chosen in such a way that, depending on the concentration of said volatile acids and the furfural in the solution to be extracted, the distribution coefficients thereof, with respect to both types of compounds are such that placed in intimate contact with the liquid to be extracted, the maximum equilibrium concentration for the acids is reached, and not for the furfural.
