SEPARATION AND DETERMINATION OF SOME AROMATIC SULFONES BY REVERSED-PHASE HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY

The reversed-phase high-performance liquid chromatography of some sele cted, industrially important aromatic sulfones has been investigated. The chromatographic behaviour of three groups of aromatic sulfones has been studied. The optimum conditions of separation and UV spectra of the sulfones and some of their hydroxy and benzyloxy derivatives are p resented. The dependences of capacity factors vs methanol content in m obile phase are mentioned. The results obtained have been applied to t he quantitative analysis of different technical-grade samples and isom er mixtures. For all the separation methods mentioned the concentratio n ranges of linear calibration curves have been determined.
