“…Catalyst stability studies demonstrated only a minor decrease in activity, after four consecutive recycling cycles [55]. The best catalytic performance between the based materials present in Table 3, is showed by a composite formed by the incorporation of a polyoxotungstate into the MOF-Fe framework [HMIm]3[PW12O40]@MOF-Fe (Table 3) [70]. This catalyst obtained complete glycerol conversion and complete solketal selectivity, after only one hour using the lowest ration glycerol/acetone reported in the literature.…”

“…This catalyst obtained complete glycerol conversion and complete solketal selectivity, after only one hour using the lowest ration glycerol/acetone reported in the literature. Using [HMIm]3[PW12O40]@MOF-Fe catalyst during seven recycling cycles, the glycerol conversion and solketal selectivity was mantained, demonstrating the superior acetalization behaviour of this catalyst compared to the isolated polyoxotungstate [70]. * wi refers to without information.…”

The valorization of the large amount of crude glycerol formed from biodiesel industry, is of primordial necessity. One possible direction with high interest to the biorefiniery sector is the production of fuel additives as solketal, though the acetalization of glycerol with acetone. This is a chemical process that conciliates high sustainability and economic interest, since solketal contributes to the fullfilment of a Circular Economy Model through its use in biodiesel blends. The key to guarantee high efficiency and high sustainability for solketal production is the use of a recovery and recyclable heterogeneous catalyst. Some examples are already reported in the literature (first example in 2012), and this review intends to conciliate the information spreaded in this topic and established the most important reacional parameters and the main catalytic characteristics strategies to achieve high solketal production in short reaction time.

“…ILs-HPAs have been used in various applications such as electrochemistry, nanotechnology, and catalysis . They have also been used in various organic reactions, such as trans-esterification, desulfurization, hydrolysis, benzyl alcohol oxidation, synthesis of cyclic carbonate, synthesis of benzaldehyde glycol acetal, acetalization of glycerol, etc. Despite the characteristics mentioned of ILs-HPAs as homogeneous catalysts, they pose some complications, including high viscosity, which affects activity, and a homogeneity nature, which leads to difficulty in the recovery of the catalyst from the reaction mixture. , Recently, the design of heterogeneous catalysts has been explored to tackle the limitations of ILs.…”

In this work, we have reported the synthesis of a series of heterogeneous catalysts, viz., [HMIm]3[PW12O40]@MOF-Fe, [HMIm]3[PMo12O40]@MOF-Fe, and [HMIm]4[SiW12O40]@MOF-Fe, by a simple impregnation method. The catalysts were characterized by several techniques, such as FTIR, EDX, XRD, SEM, elemental mapping, and TGA. Among these materials, [HMIm]3[PW12O40]@MOF-Fe had more acidic sites (confirmed by potentiometric titration) and high stability around 598 °C (confirmed by TGA). The catalytic prospect of the materials was examined through selective acetalization of glycerol to solketal as a fuel additive under solvent-free and room-temperature conditions. [HMIm]3[PW12O40]@MOF-Fe exhibited the highest catalytic activity among the three catalysts in terms of glycerol conversion (100%), solketal selectivity (100%), and solketal yield (100%). A recyclability study of [HMIm]3[PW12O40]@MOF-Fe showed that the material could be reused for up to 7 cycles with insignificant loss in its catalytic performance.
