The extraction scheme for dyes, developed previously, is applied to benzoic acid and its hydroxylated derivatives. Extractions are done with tri-n-octylamine at pH 5.5 and an ionic strength of 0.1 into chloroform. Equilibrium is attained in 20 min or less. The influences of pH and ionic strength of
