Study on proposing some environmental-friendly chemical processes


In order to convert an unusable material to a valuable material, we research to propose an environmental- friendly chemical processes. We proposed the three chemical processes shown in the figure to produce a monomer to make a bioplastic from woody biomass. As the first process, we used subcritical water to hydolyze cellulose and hemicellulose. We converted monosaccharide to 2,5-Hydroxymethylfrufral (HMF) by the quick extraction as called as “Slug Flow” as the second process. We proposed a converting chemical process using a metal catalyst with liposome, which is an artificial cell membrane, to produce 2,5-frandicarboxylic acid.



Study on a mechanism of transport phenomena between immiscible organic-water phases in Slug Flow


As mentioned above, the quick extraction is effective to produce HMF. The key factor is transport phenomena between immiscible organic-water phases in Slug Flow. We try to elucidate what is an important factor for the transport. The depth of the interface is one candidate to effect the transporting rate of HMF. The depth depends on variety of organic solvent. We also research the effect of surfactants on the depth of the interface.
