Separation of 2,6- and 2,7-dimethylnaphthalene isomers
by supercritical fluid adsorption

We are investigating the properties and phase equilibria for chemical engineering from the information of molecular level with the method of physical chemistry. The main targets of phase equilibria are the measurement and prediction of high pressure vapor-liquid equilibria and the solubilities of solutes in supercritical fluids. We produced functional materials such as functional cotton, metal + polymer complex, and titania film for dye sensitized solar cells by using supercritical fluids. We calculate the stability of gas hydrates and diffusion coefficients of hydrogen in hydrogen hydrate by molecular simulation. We study the mechanism of electro-hydrodynamic flow under applied high voltage in fluids. We also investigating the application of electro-hydrodynamic flow to the enhancement of extraction.
