Efficient heterogeneous functionalized polymer ionic liquid catalyst for the synthesis of ethylene carbonate via the coupling of carbon dioxide with ethylene oxide

Cocatalyst‐Free Hybrid Ionic Liquid (IL)‐Based Porous Materials for Efficient Synthesis of Cyclic Carbonates through a Cooperative Activation Pathway

“…Vinyl alkyl halides such as 1-butyl-3-vinylimidazolium bromide ([VBIM]Br), 1-ethyl-3-vinylimidazolium bromide ([VEIM]Br), [17] (4-vinylphenyl)methanol, [26] and SBA-15 [27] were prepared according to the literature reports. 1-Boromobutane, azobis(isobutyronitrile) (AIBN), and propylene oxide (PO) were purchased from Sinopharm Chemical Reagent.…”

“…Imidazolium (IM)-and 1,2,4-triazolium (TR)based ionic liquids( ILs) are more attractive than other metalfree catalysts owing to their high activity and selectivity. [17] Among different types of inorganic materials, mesoporous silicas with highs urface area, large pore size (2-50 nm), and controllable pore structurea re more beneficial carriers for polymers. [15] Irrespective of the variousa dvantages of ILs in catalysis, employmento fI Ls as catalysts always faces the difficulty of catalyst recyclinga nd separationa sw ell as product purification.…”

“…For example, functionalized polymer ionic liquids( PILs) have been immobilized onto a4 molecular sieve. [17] Among different types of inorganic materials, mesoporous silicas with highs urface area, large pore size (2-50 nm), and controllable pore structurea re more beneficial carriers for polymers. [18] ILs and IL-based polymers have been supported on mesoporouss ilicas, such as SBA-15 and MCM-41.…”

Synthesis, characterization and theoretical studies on novel organic–inorganic hybrid ion–gel polymer thin films from a γ-Fe2O3doped polyvinylpyrrolidone–N-butylpyridinium tetrafluoroborate composite via intramolecular thermal polymerization

“…Polymer-ionic liquid ion-gel electrolytes and thin lms have been widely explored during the past few years for applications like heterogeneous catalysis, as photonic crystal gas sensors for detecting analytes like glucose and ammonia, for transport and separation of binary gas mixtures, in proton exchange membrane fuel cells (PEMFCs), lithium ion batteries, solid state exible supercapacitors and dye-sensitized solar cells (DSSCs). [2][3][4][5][6][7][8][9] The most commonly studied polymer-ionic liquid matrix includes combinations of polymers like poly (4-vinylphenol), poly(ethylene oxide) (PEO) and poly(vinylidene uoride) (PVDF) and ionic liquids (ILs) of alkyl pyrrolidinium, alkyl imidazolium and alkyl sulfonium based cations with different types of anions. [10][11][12][13][14][15][16][17] However, not much have been studied on the scope of pyridinium based ILs in combination with polyvinylpyrrolidone (PVP) for charge storage applications.…”

Catalytic Performance of Microwave Functionalized NH<SUB>2</SUB>-MIL-53 for Cyclic Carbonate Synthesis from CO<SUB>2</SUB> and Epoxides

“…3 8-20 In addition to these highly active homogeneous systems, immobilized catalysts employing various supports such as commercial silica, MCM-41, SBA-15, and polystyrene have been explored for easy separation of the catalysts. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] Therefore, a heterogeneous catalyst which is efficient under mild reactions is still highly desirable. Metalorganic frameworks (MOFs) are a class of porous crystalline organic-inorganic hybrid compounds formed by coordination of metal clusters or ions with multi-dentate organic linkers.…”
