Some aspects on the constitution of egyptian bagasse pith‐phenol polycondensate resins. Part I. Elemental analysis and thin layer chromatography‐ultra violet combined technique

In order to investigate the chemical constitution of bagasse pith‐phenol polycondensate resin, different resins were prepared by condensation of phenol with compounds that may be produced during the acid hydrolysis of bagasse pith and with different constituents of bagasse pith. The optimum conditions for thin layer chromatographic separation of these polycondensate resins were determined. The proposed chemical structure and the pattern of chemical reactions were discussed on the bases of elemental analysis, TLC and UV spectroscopic studies.
