Etude des dérivés liquides du charbon : séparation et identification des composés aromatiques hydroxyles

Abstract : Different analytical techniques were used the study of a low temperature pyrolysis coal tar rich in hydroxyaromatic and we give special attention to the phenolic compounds separation : the primary fractionation with a distillation apparatus, the distact; the non aqueous anion exchange separation with quasi quantitative recovery of acid fractions; the identification and determination of hydroxyle functions by fourier transform infrared spectroscopy, enthalpimetric titration and by fluor-19 nuclear magnetic resonance after trifluoroacetylation; the analysis by one dimensional (proton and carbon-13) and two dimensionals nuclear magnetic resonance spectroscopy; the analysis by electron impact mass spectrometry coupling; low voltage-low resolution; low voltage-high resolution. Finally, the application of the structural group analysis method has allowed the interpretation of the main results obtained
