| Outline of Final Research Achievements |
For developing synthesis methods hydrocarbon by hydrogenolysis of cellulose in ionic liquid－supercritical CO2 biphasic systems, high pressure densities and CO2 solubilities were measured. Theoretical methods were developed for estimating both CO2 and H2 solubilities in ionic liquids. An apparatus for designed, built and tested for measuring H2 gas solubility in the presence of CO2 with ionic liquids. A theoretical metric, denoted as the enhancement ratio (ER) was proposed and used to assess the increase or decrease that H2 solubility that can be obtained with supercritical CO2. Ionic liquids that dissolve biomass were theoretically assessed with the metric and equations of state. The enhancement of H2 solubility by CO2 was observed from experimental measurements. The properties measured and the theoretical methods developed allow estimation of reaction conditions for the synthesis of many types of chemicals derived from cellulose.
