“…The reaction conditions were 3 times the stoichiometric value of 2-cyanopyridine, 150°C, 4 MPa and 5 h. The catalyst could be easily recycled through the calcination process at 400°C for 5 h, and the activity of the regenerated catalyst stayed constant after recycling for five times. To enhance the catalytic performances, Zr doped CeO 2 was used and the influence of molar ratio of Zr/Ce on the crystalline structure, surface composition, redox and acid-base properties were studied (Liu et al, 2018). The conversion of glycerol increases to 40% and the yield of GC to 36.3% in presence of a 0.02 molar fraction of Zr.…”

The state of the art on the glycerol carbonate (GC) synthesis has been updated since the last published reviews in 2012, 2013, and 2016. Three types of reactions continue to be studied: glycerolysis of urea, transcarbonation of DMC, DEC, or cyclic carbonates with glycerol and reaction using CO 2 . Among these different routes, DMC and glycerol were selected as the raw materials for the GC synthesis in this work since the transcarbonation from these green reagents leads to high yields and selectivities, using mild conditions including a less energy consuming GC separation process. Catalytic conditions using Na 2 CO 3 seem to be a good compromise to achieve a high yield of GC, leading to an easier purification step without GC distillation. Mild temperatures for the reaction (73–78°C) as well as a low waste amount confirmed by the E-factor calculation, are in favor of controlled costs. Plasticizing properties of synthesized GC were compared to the behaviors of a commercial plasticizer and natural dialkyl carbonates, for a colorless nail polish formulation. The resulting films subjected to mechanical and thermal stresses (DMA and Persoz pendulum) showed the high plasticizing effect of GC toward nitrocellulose based films, probably due to hydrogen bond interactions between GC and nitrocellulose. The GC efficiency gives the possibility to decrease the content of the plasticizer in the formulation. Glycerol carbonate can be thus considered as a biobased ingredient abiding by the green chemistry concepts, and safe enough to be used in an ecodesigned nail polish formulation.

“…Some papers showed the excellent performance of activated carbon for catalyzing the conversion of glycerol to solketal ( Table 7) and some of these exhibited a high activity and selectivity under green conditions (solvent-free conditions at a mild temperature). The high surface area of activated carbon preserves the higher surface acid sites by some modification, including acid, metal, and composite modifications [24,[95][96][97]. Therefore, they are promising candidates as heterogeneous catalysts for the acetalization of acetone with glycerol.…”

Glycerol to Solketal for Fuel Additive: Recent Progress in Heterogeneous Catalysts

et al. 2019

Biodiesel has been successfully commercialized in numerous countries. Glycerol, as a byproduct in biodiesel production plant, has been explored recently for fuel additive production. One of the most prospective fuel additives is solketal, which is produced from glycerol and acetone via an acetalization reaction. This manuscript reviewed recent progress on heterogeneous catalysts used in the exploratory stage of glycerol conversion to solketal. The effects of acidity strength, hydrophobicity, confinement effect, and others are discussed to find the most critical parameters to design better catalysts for solketal production. Among the heterogeneous catalysts, resins, hierarchical zeolites, mesoporous silica materials, and clays have been explored as effective catalysts for acetalization of glycerol. Challenges with each popular catalytic material are elaborated. Future works on glycerol to solketal will be improved by considering the stability of the catalysts in the presence of water as a byproduct. The presence of water and salt in the feed is certainly destructive to the activity and the stability of the catalysts.

“…It has also been proposed as a monomer in polymer synthesis and as an alternative green solvent in Li‐ion batteries [12,14,17] . The synthesis of glycerol carbonate can be achieved through the reaction of glycerol with different compounds acting as carbonyl sources, such as carbon monoxide, [18,19] phosgene, [20] carbon dioxide, [18,21] urea, [22,23] and organic carbonates [13,24,25] . However, most of these routes present major issues such as: (i) the toxicity of the reagents, as in the case of phosgene and carbon monoxide; [12,15] (ii) the thermodynamic limitation associated with direct reaction with carbon dioxide, which can be only partially mitigated using sacrificial dehydrating agents ( e. g .…”

One‐pot Fixation of CO₂ into Glycerol Carbonate using Ion‐Exchanged Amberlite Resin Beads as Efficient Metal‐free Heterogeneous Catalysts

2020

The one‐pot synthesis of glycerol carbonate from carbon dioxide and glycerol was achieved using ion‐exchanged Amberlite resin beads as metal‐free heterogeneous catalysts. Two commercially available Amberlite resin beads consisting of polystyrene cross‐linked with divinylbenzene and functionalized with either trimethyl ammonium chloride (IRA‐900) or dimethyl ethanol ammonium chloride (IRA‐910) groups were used as starting materials to prepare the catalysts. These polymeric beads were transformed into their iodide (Amb‐900‐I, Amb‐OH‐910‐I) or hydroxide (Amb‐900‐OH and Amb‐OH‐910‐OH) counterparts through straightforward ion‐exchange reactions. First, the two resin bead catalysts in hydroxide form were tested in the base‐catalyzed transcarbonation reaction of glycerol with propylene carbonate. Both resin bead catalysts were more active compared to benchmark basic catalysts as hydrotalcites and attained 80 % yield of glycerol carbonate over Amb‐OH‐910‐OH after 2 h at 115 °C, employing a 4 : 1 ratio between propylene carbonate and glycerol. Then, the one‐pot reaction of CO2, glycerol and propylene oxide to produce propylene carbonate, glycerol carbonate and propylene glycol was investigated as the main target of this study. The reaction involves two steps: the reaction of propylene oxide with CO2 yielding propylene carbonate, and the transcarbonation of the formed cyclic carbonate with glycerol. Amb‐900‐I, Amb‐OH‐910‐I, Amb‐OH‐910‐OH and combinations of the latter two were employed as catalysts. Although Amb‐OH‐910‐I alone is poorly active in the transcarbonation reaction, it showed the highest catalytic activity in the one‐pot cascade reaction, surprisingly surpassing the performance of the Amb‐OH‐910‐I/Amb‐OH‐910‐OH mixtures and reaching high yields of glycerol carbonate (81 %, 115 °C, 4 h). These findings led to proposing a mechanism for the one‐pot reaction using the Amb‐OH‐910‐I catalyst. The bead format led to easy recovery of the catalyst, which displayed good reusability in consecutive runs.
