Abstract:In this study, gallic acid was separated by triphenylphosphine oxide in
the presence of conventional solvents. Triphenylphosphine oxide is an
organophosphorus extractant and highly selective towards carboxylic
acids. Reactive extraction results were compared with physical
extraction results. The extraction efficiencies reached up to 61, 76,
86, 67, and 84 % in the presence of triphenylphosphine oxide with oleyl
alcohol, dimethyl adipate, isobutanol, methyl isopropyl ketone, and
methyl ethyl ketone, respectivel… Show more
