“…The peak at 1416 cm −1 is due to the oxalate vibrational frequency in BaZrO 3 . The peak at 560 cm −1 corresponds to the Zr present in the octahedral site in the perovskite structure [39] . Hence, FTIR study also confirms the presence of three phases viz.…”

Efficient and highly selective isomerization of glucose to fructose was achieved by using the inexpensive Ba−Zr mixed metal oxide catalyst. Catalyst was prepared by varying Ba−Zr ratios using co‐precipitation method. Various phases formed, planes exposed, morphology, elemental composition and particle size, basic site density and strength, oxidation state of elements were well studied by using various characterization techniques. The XRD analysis clearly indicates the presence of Ba+2 and Zr+4 in the form of BaO, ZrO2 and BaZrO3 phases. The SEM and HR‐TEM images indicate that, Ba−Zr (2 : 1) catalyst prepared showed uniform morphology with spherical and rod‐shaped particles ranging from 300 to 600 nm. Under the optimized reaction conditions Ba−Zr (2 : 1) catalyst exhibited excellent results in terms of 57 % of glucose conversion with 89 % selective formation of glucose. The presence of both acidic as well as basic sites play vital roles in activating the substrate molecules to selectively yield fructose. Ba−Zr (2 : 1) catalyst showed excellent recyclability performance up to four recycles.

“…The reaction of FA with (biomass-derivable) ethanol gives 2-(ethoxymethyl)furan (EMF) and ethyl levulinate (EL) (Scheme 1) [121]. The applications of EMF include bio-solvent [122], pharmaceuticals, food flavor [123][124][125][126], aging flavor for beer storage [127][128][129][130][131] or white wine [132] and fuel additive [122,[124][125][126][133][134][135][136][137] since it has a high energy density, cetane number [138] and capacity to reduce soot emissions [124,134,139,140]. On the other hand, EL is an attractive oxygenated fuel extender (its high oxygen content enhances engine efficiency, improves flow properties, etc.…”

“…The total selectivity (EMF plus EL) was higher for 1 (90%) than for MIL-101(Cr)-SO 3 H (79%) [146,147]. A detailed comparison of the catalytic results for 1 to literature data for other types of solid acid catalysts is given in the Supplementary Material Section 3 [121,126,134,136,137,[145][146][147]157,. Overall, the catalytic performance of 1 seemed to stand on an intermediate footing among the various types of solid acid catalysts reported in the literature for the FA/ethanol system (e.g., commercial zeolites and acid resins, and modified metal oxides).…”

Versatile Coordination Polymer Catalyst for Acid Reactions Involving Biobased Heterocyclic Chemicals

The chemical valorization/repurposing of biomass-derived chemicals contributes to a biobased economy. Furfural (Fur) is a recognized platform chemical produced from renewable lignocellulosic biomass, and furfuryl alcohol (FA) is its most important application. The aromatic aldehydes Fur and benzaldehyde (Bza) are commonly found in the slate of compounds produced via biomass pyrolysis. On the other hand, glycerol (Gly) is a by-product of the industrial production of biodiesel, derived from fatty acid components of biomass. This work focuses on acid catalyzed routes of Fur, Bza, Gly and FA, using a versatile crystalline lamellar coordination polymer catalyst, namely [Gd(H4nmp)(H2O)2]Cl·2H2O (1) [H6nmp=nitrilotris(methylenephosphonic acid)] synthesized via an ecofriendly, relatively fast, mild microwave-assisted approach (in water, 70 °C/40 min). This is the first among crystalline coordination polymers or metal-organic framework type materials studied for the Fur/Gly and Bza/Gly reactions, giving heterobicyclic products of the type dioxolane and dioxane, and was also effective for the FA/ethanol reaction. 1 was stable and promoted the target catalytic reactions, selectively leading to heterobicyclic dioxane and dioxolane type products in the Fur/Gly and Bza/Gly reactions (up to 91% and 95% total yields respectively, at 90 °C/4 h), and, on the other hand, 2-(ethoxymethyl)furan and ethyl levulinate from heterocyclic FA.

“…These specific limitations of the FA alkylation require the search for other methods for the preparation of alkyl furfuryl ethers. Recently ethyl furfuryl ether was obtained by direct alkylation of FA by the ethanol on a zirconium-modified SBA-15 catalyst with a yield up to 87 % [13].…”

The process of catalytic hydrogenation of furfural diethyl acetal to ethyl furfuryl ether on the different catalysts (palladium, palladium-rhenium and copper-ruthenium on Sibunit in reduced forms) was studied. It was found that hydrogenation of the furan ring with the formation of THF diethyl acetal occurs on all the catalysts. Ethyl furfuryl ether becomes the main product while carrying on the second hydrogenation cycle on spent palladium catalyst (yield and selectivity up to 55 % and 85 %, respectively)
