Structure investigation of xylenols and their redox products by thermal and spectral methods of analysis

ABSTRACT

The structures of 2,6- and 3,4-xylenols together with their iodine redox products 1-3 were studied and critically investigated. Characterization of these materials involved elemental, thermogravimetric, differential thermogravimetric and differential thermal analyses. IR and NMR spectrometry were used for the study of structural formulae of the obtained redox products. The identification and characterization of these materials confirmed the proposed schemes representing redox reactions of xylenols with iodine. It also explained the schemes representing fragmentation of the investigated compounds by thermal analyses. Thin layer chromatography was also used for separation and identification of redox products obtained in the reaction media
