The ion association reaction between aromatic anions and quaternary
ammonium ions in aqueous solutions was investigated through mobility
changes in capillary electrophoresis. The electrophoretic mobility of
aromatic anions decreased with increasing amount of quaternary ammonium
salt added to the migrating solutions. The change in mobility of anions
due to the ion association was found and was treated with a least-squares
method, giving ion association constants. The ion associability order of
the isomers of aromatic anions was found to be
naphthalene-2,6-dicarboxylate > naphthalene-2,3-dicarboxylate,
naphthalene-2-sulfonate > naphthalene-1-sulfonate and terephthalate
> isophthalate > phthalate. The order of the ion associability of
naphthalene-1,5- and -2,6-disulfonate reversed depending on the alkyl
chain length of the pairing cation. The order of ion associability of
quaternary ammonium ions was found to be tetraamylammonium >
tetrabutylammonium > tetrapropylammonium ≈ octyltrimethylammonium
≈ hexyltrimethylammonium > tetraethylammonium >
tetramethylammonium, and suggested that ion association in aqueous
solution was governed by the hydrophobicity of the pairing cation.
