A green technique for non-catalytic solubilization and hydrolysis of crystalline cellulose
Keywords:Non-catalytic, hydrolysis, microcrystalline cellulose, strong gravitational field, guaiacol derivatives
A unique method was established for the decomposition of cellulose using a strong gravitational field at room temperature to recover useful chemical intermediates. Experiments of decomposition of microcrystalline cellulose were conducted at room temperature for 24 hours to a gravitational field of 0.33 x 106 G generated by an ultracentrifuge rotating at 80,000 rpm using a speciallydesigned gravity apparatus. After gravity experiment, we analyzed the compounds by LC-MS spectra and HPLC respectively and showed that stronggravity treatment of microcrystalline cellulose was successfully hydrolyzed to form cello-oligosaccharides and glucose, and surprisingly phenolic compounds such as guaiacol derivatives.
