Mesoporous tin phosphate as an effective catalyst for fast cyclodehydration of bio-based citral into p-cymene

Acetalization strategy in biomass valorization: a review

“…[1][2][3][4][5][6][7] Lignocellulose and vegetable oil, the main solid and liquid components of biomass, represent sustainable carbon sources to produce transport fuels and valuable chemicals. [8][9][10][11][12][13][14][15] The catalytic conversion of lignocellulose/ vegetable oil and their related derivatives has attracted great attention in biomass valorization. [16][17][18][19][20][21][22][23][24][25] Many elegant methods including hydrolysis, dehydration, hydrogenation, hydrogenolysis, oxidation, etherification, esterification, amination, aldol condensation, Diels-Alder, Knoevenagel condensation, and acetalization have been developed for the valorization of lignocellulose/vegetable oil derivatives toward value-added chemicals and biofuels.…”

Synthesis of renewable C–C cyclic oxygenated compounds dedicated for high-density biofuels from biomass-derived cyclopentanone

“…[4][5][6] Nowadays, biomass-derived platform molecules play a significant role in the linkage of lignocelluloses and bio-fuels as well as valueadded chemicals. [7][8][9] Various platform molecules, such as furfural, 5-hydroxymethylfurfural, levulinic acid, g-valerolactone and cyclopentanone, are accessible from lignocelluloses with high yields. [10][11][12][13] However, those as-obtained bio-based platform compounds normally have only two to six carbon atoms, and their direct hydrodeoxygenation results in the formation of final hydrocarbons that do not meet the requirements of transportation fuels (usually containing 9-22 carbon atoms).…”

Effective one‐pot tandem synthesis of γ‐valerolactone from biogenic furfural over zirconium phosphate catalyst

“…Metal phosphates are very popular heterogeneous catalysts in biomass valorisation owing to their Lewis-Brønsted dual acidity and structural controllability as well as diversity of synthesis methods. [40][41][42][43] Simultaneously, Zr-based catalysts take prevalence in GVL synthesis from levulinic acid or its esters, [44][45][46][47] which give us the enlightenment that zirconium phosphate is probably capable of catalyzing the one-pot tandem transformation of furfural into GVL. In this work, zirconium phosphates (ZrPO) were successfully prepared by different methods (i.e., hydrothermal method and Scheme 1.…”
