| Outline of Final Research Achievements |
We have succeeded in hydrolyzing hesperidin (HPD) to hesperetin (HPT) in the temperature range of 150 to 200 ℃, and pressures of 15 to 25 MPa obtaining about 2-fold increase in yield compared to the conventional method using our proposed novel reactive separation process utilizing the synergy of SCCO2 and subcritical H2O. Simultaneous and selective separation of HPT was achieved by simply passing SCCO2 through the reaction products. International collaboration has started which includes Valladolid University on the use of visual cell and Raman spectroscopy. The application of this novel approach was further extended to include conversion of biomass to platform chemicals and fuels in collaboration with Universiti Teknologi PETRONAS, University of the Philippines and De La Salle University. Our future studies will include elucidating the reaction mechanism taking place in the proposed system using quantum calculation techniques and molecular dynamic simulations.
