Key words: inverse gas chromatography, cation resin, ionite, Bisphenol A, acid-base interactions, catalysis
The inverse gas chromatography method have been used for estimation
of relative number of acid and base active centres for two type cation
exchangers that are used as catalysts of Bisphenol A industrial synthesis.
It was stated that after a few weeks of the continuous work of reactors
filled with the catalysts, the acid-base properties of the latter have
undergone significant changes. The number of acid centres decreased while
the number of base centres increased. Simultaneously, the decreased of
the yield of the synthesis product was observed.
