ABSTRACT:
According to the process of the present invention, alcohols are recovered from aqueous mixtures thereof with a concentrated strong acid by contacting such alcohol-containing aqueous concentrated acid mixtures with a carboxylic acid selected from the group consisting of acids of the formula RCO.sub.2 H wherein R is a straight or branched-chain or cyclic alkyl of from 5 to 19 carbon atoms per molecule to form an extract phase containing the carboxylic acid in addition to said alcohol, and an aqueous raffinate phase depleted in the alcohol.
