The extraction of phenols from dilute aqueous solutions was studied; the extracting agents were n-butyl acetate, C/sub 5/-C/sub 10/ alcohols, nitrobenzene, and tributyl phosphate. Isotherms of extraction of phenol by isomolar mixtures of n-butyl acetate and nitrobenzene, n-hexyl alcohol and tributyl phosphate are shown. The synergistic and salting out effects in extraction of phenol with mixtures of solvents are represented based on n-butyl acetate. The effect of dialkyl phthalates on extraction of pyrocatechol with C/sub 5/-C/sub 10/ alcohols was studied; in extraction of pyrocatechol with solutions of dialkyl phthalates in alcohols, synergism was observed.
