Xu, Jingyu; Jia, Hongge; Yang, Nan; Wang, Qingji; Yang, Guoxing; Zhang, Mingyu; Xu, Shuangping; Zang, Yu; Ma, Liqun; Jiang, Pengfei; Zhou, Hailiang; Wang, Honghan published the artcile< High efficiency gas permeability membranes from ethyl cellulose grafted with ionic liquids>, SDS of cas: 700370-07-6, the main research area is ethyl cellulose ionic liquid membrane elastic modulus gas permeability; ethyl cellulose; gas permeation properties; imidazole; liquid; membrane.
Et cellulose was grafted with ionic liquids in optimal yields (62.5-64.1%) and grafting degrees (5.93-7.90%) by the esterification of the hydroxyl groups in Et cellulose with the carboxyl groups in ionic liquids In IR spectra of the Et cellulose derivatives exhibited C = O bond stretching vibration peaks at 1760 or 1740 cm-1, confirming the formation of the ester groups and furnishing the evidence of the successful grafting of Et cellulose with ionic liquids The Et cellulose grafted with ionic liquids could be formed into membranes by using the casting solution method. The resulting membranes exhibited good membrane forming ability and mech. properties. The EC grafted with ionic liquids-based membranes demonstrated PCO2/PCH4 separation factors of up to 18.8, whereas the PCO2/PCH4 separation factor of 9.0 was obtained for pure EC membrane (both for CO2/CH4 mixture gas). The membranes also demonstrated an excellent gas permeability coefficient PCO2, up to 199 Barrer, which was higher than pure EC (PCO2 = 46.8 Barrer). Therefore, it can be concluded that the ionic liquids with imidazole groups are immensely useful for improving the gas separation performances of EC membranes.
