“…19,20 However, unsupported heteropoly acids have high solubility in polar media and low surface area, which limit their industrial applications. [21][22][23] Therefore, the design of heteropoly acids encapsulation into the excellent and stable porous supported for biodiesel production is still a great challenge.…”

“…A heteropolyacid (HPA) contains metal atoms such as W, Mo, and V, and p -block elements such as P, Si, etc. ; the oxygen atoms connecting the metal atoms and H + ions for charge balancing are generally used for recycling acidic catalysts for the synthesis of fine chemicals ( Yan et al, 2013 ; Wu et al, 2016a ; Wu et al, 2016b ; Wu et al, 2016c ; Zhou et al, 2016 ; Manikandan et al, 2017 ; Ramli et al, 2017 ; Zhang et al, 2017 ; Luan et al, 2018 ; Vilanculo et al, 2018 ; Lucas et al, 2019 ). Numerous structural analogs can be synthesized by either replacing the metal or nonmetal atoms.…”

Biomass, the only globally available, renewable feedstock of organic carbon, is considered a viable alternative to fossil fuels. It can be efficiently utilized to produce various building blocks in accordance with green and sustainable chemistry principles. In this review, recent progress, such as the transformation of carbohydrates (C5 or C6 sugar, inulin, and cellulose) and their derivatives (furfural, hydroxymethylfurfural) into significant platform chemicals over polyoxometalates, zeolites, non-noble metals, and ionic liquids in single or multiphase, is evaluated.

“…The LA esterification reaction has been investigated using several solid acid catalysts toward the production of ALs in comparatively high yields (Pileidis and Titirici, 2016). Heteropolyacid (HPA) is a special species of acid composed of a combination of certain metals (tungsten, molybdenum, or vanadium) and p-block non-metals (silicon, phosphorus, or arsenic) with acidic hydrogen and oxygen atoms, which are generally applied as reusable acid catalysts for the preparation of fine chemicals (Yan et al, 2013;Wu et al, 2016a,b,c;Zhou et al, 2016;Manikandan and Cheralathan, 2017;Ramli et al, 2017a;Zheng et al, 2017;Luan et al, 2018;Vilanculo et al, 2018;Lucas et al, 2019). Numerous structural combinations can be prepared upon adjusting the metal and non-metal used.…”

Biomass is a potential non-food, carbon-neutral, and abundant resource, which can be used as an alternative to fossil fuels during the sustainable preparation of various platform chemicals. Alkyl levulinates (ALs) have found widespread application as flavorings, plasticizing agents, and fuel additives, as well as synthetic precursors to various building blocks. Several processes have been investigated to transform biomass and its derivatives into ALs, which mainly include: (i) direct esterification of levulinic acid (LA) with alkyl alcohols and (ii) alcoholysis reactions of renewable biomass feedstocks and their derivatives, including furfuryl alcohol (FAL), chloromethyl furfural (CMF), and saccharides. This review focuses on illustrating the effects of the biomass pretreatment step, catalyst texture, possible mechanisms, acidities, and intermediates on the synthesis of ALs from sustainable resources covering a wide range of intermediates, including diethyl ether (DEE), 4,5,5-triethoxypentan-2-one (TEP), ethoxymethylfuran (EMF), ethyl-D-fructofuranoside (EDFF), and ethyl-D-glucopyranoside (EDGP).
