Sugar-cane bagasse was liquefied in ethylene glycol/phthalic anhydride mixture catalyzed by sulphuric acid at temperatures 160-220°C, liquefaction times 60-240 minutes, and ethylene glycol amounts 5-20 ml for each three grams of sugar-cane bagasse. The residue obtained was characterized by FT-IR, X-ray diffraction, and scanning electron microscope. The percentages of residue, average molecular weight, hydroxyl and acid numbers were determined as an estimate of polyol value of the liquid products. Optimal conditions for liquefaction were established: reaction temperature 160°C, reaction time 180 minutes, and ethylene glycol amount 20 ml/three grams sugar-cane bagasse.

The residue obtained was characterized by FT-IR, X-ray diffraction, and scanning electron microscope. The percentages of residue, average molecular weight, hydroxyl and acid numbers were determined as an estimate of polyol value of the liquid products. Optimal conditions for liquefaction were established: reaction temperature 160°C, reaction time 180 minutes, and ethylene glycol amount 20 ml/three grams sugar-cane bagasse.
