| Outline of Final Research Achievements |
We focused on acetylated-cyclodextrins (AcCD) to obtain the membrane materials consisting of CA and AcCD as a microporous material. Separation membranes CA/AcCD were prepared by cellulose acetate (CA) and containing up to 50wt% AcCD. Permeability coefficients (P) and ideal separation factor (α) of CA/AcCD were measured at 2 atm and 35°C for He, H2, O2, N2, CH4 and CO2 gases by the vacuum time-lag method. CA/AcCD was obtained as a transparent membranes having a thickness in the range of 14~47μm. Compared to CA, P values of CA/AcCD increased, and in the case of CH4 gas that was the largest kinetic diameter of gas molecules, the P values more increased. Gas permeation properties of the membrane were confirmed using AcCD which blocked micro pores with molecular inclusion, and it was found that the gas did not permeate the pores of CD in the membrane.
