“…Moreover, separating and recovering the used ILs from the reaction mixtures will consume a lot of energy [17]. These problems can be solved by immobilizing functionalized ILs onto solid support [18][19][20][21][22][23][24][25]. Immobilization of the functionalized ILs not only possesses much higher efficiency, but also faciliate the separation of reactants and catalyst.…”

“…As the temperature increased from 50 C to 350 C, three bands at 1111, 1155 and 620 cm À1 appeared and increased gradually, which were assigned to an -SO 3group, 36 an -O-SO 3group, 36,37 S]O and S-O group, 38 respectively. When the temperature was below 150 C, a broad band at 1280 cm À1 and three small bands at 1046, 578 and 784 cm À1 appeared, which had no obviously change below 150 C. According to the previous study, [39][40][41] the bands at 1280, 1155, and 1046 cm À1 were assigned to bidentate sulfate, which were formed by the n3 splitting of the S-O group. And the band at 578 cm À1 might be attributed to the characteristic frequencies of the SO 4 2À ion.…”
