“…The first report of immobilized IL-based catalysts was reported by Wang et al, who employed tetrabutylammonium halides immobilized on SiO 2 by a simple adsorption method [90]. The activity of the catalyst was comparatively low, as good PC yield could be obtained only after 10 h at 150 °C and 8 MPa CO 2 pressure.…”

This review presents the synergistic effect in the catalytic system of ionic liquids (ILs) for the synthesis of cyclic carbonate from carbon dioxide and epoxide. The emphasis of this review is on three aspects: the catalytic system of metal-based ionic liquids, the catalytic system of hydrogen bond-promoted ionic liquids and supported ionic liquids. Metal and ionic liquids show a synergistic effect on the cycloaddition reactions of epoxides. The cations and anions of ionic liquids show a synergistic effect on the cycloaddition reactions. The functional groups in cations or supports combined with the anions have a synergistic effect on the cycloaddition reactions. Synergistic catalytic effects of ILs play an important role of promoting the cycloaddition reactions of epoxides. The design of catalytic system of ionic liquids will be possible if the synergistic effect on a molecular level is understood.

“…Moreover, a possible utilization of cyclic carbonates, such as propylene carbonate (PC) and ethylene carbonate (EC), is the transesterification with methanol to form dimethyl carbonate (DMC) and the corresponding glycol. Especially, the synthesis of DMC from methanol and PC is widely used in the industrial synthetic process and regarded as a process utilizing carbon dioxide as a raw material due to that PC could be effectively synthesized via the cycloaddition of propylene oxide (PO) and carbon dioxide [4][5][6][7][8]. In addition, there are some other methods for the synthesis of DMC via carbon dioxide, which include direct synthesis from carbon dioxide and methanol [9][10][11][12][13] and alcoholysis of urea with methanol [14][15][16].…”

Alkali carbonates were first used as effective catalysts for the synthesis of propylene carbonate from propylene glycol and carbon dioxide in the presence of acetonitrile. Acetonitrile in the reaction acted as not only the solvent but also the dehydrating reagent to remove the water produced from the reaction. Interestingly, upon ammonium carbonate being introduced into the reaction system, the catalytic selectivity was significantly enhanced.

“…The synthesis of cyclic carbonates through cycloaddition of CO 2 to epoxides is one of the few commercial routes that use CO 2 as a raw material (Scheme 5). In the past decades, a number of homogeneous and heterogeneous catalysts have been developed for the cycloaddition reaction, such as phosphines [32][33][34], organic bases [35][36][37], ionic liquids [1,[38][39][40][41][42][43], organometallic complexes [44][45][46][47][48][49][50][51][52][53][54][55][56][57][58], metal oxides [59][60][61][62][63][64], modified zeolites and smectites [65][66][67][68][69], and supported catalysts [70][71][72][73][74][75][76][77]. There are reports on organometallic complexes of Cr, Co, Ni, Al, Mn, Zn, Ru, Re...…”

In this article, we present our research results on chemical fixation of CO 2 using organobismuth compounds. We fabricated bismuth biphenoate complex, Zn-Mg-Al composite oxides, and SBA-15 or Al-SBA-15 immobilized hydroxyl ionic liquid for CO 2 cycloaddition onto epoxides. The hypervalent bismuth compounds show good ability for association and dissociation with CO 2 . The bismuth biphenolate complexes are catalytically effective for the cycloaddition reaction. The heterogeneous catalysts, viz. Zn-Mg-Al oxides and SBA-15 or Al-SBA-15 immobilized ionic liquid, are efficient for the synthesis of cyclic carbonate from CO 2 and epoxide. It is found that the presence of a trace amount of water can improve the catalytic activity of the immobilized ionic liquid.
