Fourteen ionic liquids (ILs) were obtained and characterized by nuclear magnetic resonance and infra-red spectroscopy. One of these liquids, n-butylammonium acetate, was used in the treatment of coir fiber prior to acid hydrolysis. For this purpose, the fiber was pulped with 8% (w/w) sodium hydroxide for 6 h under 2.5 atm pressure at 137 °C and then treated with IL for 2 h at 90 °C. The samples were hydrolyzed in acetic acid at different concentrations and temperatures. The reducing sugar concentrations were determined in all samples, and the optimal hydrolysis conditions were established (32.2% acetic acid at 122.4 °C). The reaction time was also studied, and the conversion was maximized at 3 h. Under the best hydrolysis conditions, crude fiber, pulping fiber, and IL-treated fiber were hydrolyzed to yield 8.53%, 47.58%, and 89.75% of reducing sugars, respectively.

Amphotericin B and itraconazole were used to demonstrate that ionic liquids can be designed or chosen to provide tunable hydrophilicity in one ion and lipophilicity in the other allowing one to match the structural requirements needed to solubilize poorly water soluble active pharmaceutical ingredients. These liquid, amphiphilic excipients could be used as both drug delivery systems and solubilization agents to improve the aqueous solubility of many drugs. The solubility in deionized water, simulated gastric fluid, simulated intestinal fluid, and phosphate buffer solution was greatly improved over current methods for drug delivery by utilizing designed ionic liquids as excipients.
