Ion exchange in sulfonate additives
The ion exchange rate for sulfonate additives on KU-2-8 cation exchange resin depends on the nature of the solvent. Equilibrium is reached more rapidly in single-phase mixtures of an aprotonic and a protolytic solvent.
Ion exchange of sulfonate additives in a benzene-ethanol medium (7/3 ratio) proceeds quantitatively, without losses; no side reactions are observed.
In laboratory practice, it is advisable to replace acid hydrolysis of sulfonate additives by ion exchange on KU-2-8 cation exchange resin under the indicated conditions.
