Abstract

An IR spectroscopic investigation of extraction system components was carried out to study the complexation in the extraction of acetic, monochloroacetic, dichloroacetic, and trichloroacetic acids into benzo-15-crown-5 in chloroform. It was shown that acid extraction into chloroform (blank extraction) may give adducts via two mechanisms involving either the chloroform hydrogen atom and the carbonyl oxygen of the acid or the chloroform hydrogen atom and the chlorine atom of the chloroacetic acids. A spectral criterion for the complexation with benzo-15-crown-5 was proposed. It was shown that the extractable complexes incorporate water molecules.
