| Outline of Final Research Achievements |
Furfural is the dehydration product of xylose and it is commercially important for the production of various organic chemicalsis. The traditional processes for the production of furfural from xylose, which can be obtained from hemicellulose, are carried out by homogeneous acid such as sulfuric acid, hydrochloric acidin aqueous solution. However, conventional processes are not economically and environmentally feasible in many cases.
In this work, we studied the dehydration of xylose to furfural using various solid acids in water and simultaneous extraction with supercritical carbon dioxide, for the development of new green process.The furfural yield was increased by using semi-batch reactor system with continuous carbon dioxide flow. The furfural yield from xylose reached 55% at 443K, 20MPa using Amberlyst70 with the carbon dioxide flow rate of 0.94g/min.
