Acetone containing tetraalkylammonium chloride is found to be an efficient solvent for cellulose. The addition of an amount of 10 mol% (based on acetone) of well-soluble salt triethyloctylammonium chloride (Et3 OctN Cl) adjusts the solvent's properti

The tosylation of cellulose in the eco-friendly solvent NaOH–urea in the presence of the nonionic surfactant polyethylene glycol alkyl-(C11–C15) ether (Imbentin) yields well soluble p-toluenesulfonic acid esters of cellulose (tosyl cellulose). Th
