The products obtained from liquefaction of sugar cane bagasse with monoethanolamine were characterized using a variety of methods: elemental analysis and UV-visible, FTIR, H1NMR and C13NMR spectrometries. The oils were separated by conventional solubility techniques and were further fractionated into eight fractions (saturated, monoaromatic, diaromatic, triaromatic and poliaromatic hydrocarbons, resins, asphaltenes and pre-asphaltenes). These fractions were characterized by capillary gas cromatograpy with flame ionization detection and gas chromatography/mass spectrometry. Data obtained from simulated distillation of the oils provided useful information regarding product quality.
