Abstract

The occurrence of side chemical reactions during regeneration of the highly basic anion exchanger AB-17-2P with adsorbed vanillin with an alkali solution in the presence of atmospheric oxygen was confirmed by the method of gas chromatography/mass spectrometry. A number of the vanillin transformation products were identified. The method of mass spectrometry with matrix-activated laser desorption/ionization demonstrated the presence of the products of vanillin oxidation and polymerization, as well as benzoin condensation in the studied regeneration solution.
