Abstract
The distribution coefficients and the recovery of aminobenzoic acids i n systems with alcohols, ketones, and esters partially or completely s oluble in water were found. A procedure for the selective conductometr ic determination of aminobenzoic acids in a tert-butanol-based extract at a level of 1 mg/L (a 10-fold amount of one of the components cause d no interference) with a precision of 5-7% was proposed.
