Extraction of Hydroxycarboxylic Acids with MIBK/Toluene Solutions of Amines

摘要

Studies are reported on the extraction of glycolic, malic, and citric acids by alamine 336 and tri-n-octylamine dissolved in MIBK/toluene mixture (1:1 volume ratio). The effects of amine type and concentration on extraction of hydroxycarboxy-lic acids by amines are investigated. Formation of acid amine complexes is a dominating factor in the system under consideration.. The distribution coefficients and loading factors are calculated and reported.
