Modified boehmite: a choice of catalyst for the selective conversion of glycerol to five-membered dioxolane

Abstract

The choice of active site and support matrix decides the activity of catalyst. Any modifications on these will have a significant impact on its reactivity and selectivity. Here we have...

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

“…Synthesis of bio-fuels and valuable chemicals using renewable biomass as starting feedstock has attracted much attention since utilizing biomass is conducive to achieving the carbonneutral goal and alleviating environmental pollution caused by the overexploitation of petroleum-based resources. [1][2][3] The main component of biomass is lignocellulose which is constituted by cellulose, hemicellulose and lignin, widely available in the form of nonedible agricultural and forestry waste. [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.…”

Diaspore as an efficient halide-free catalyst for the conversion of CO2 into cyclic carbonates

“…[31][32][33][34][35] However, it is less explored as a catalyst, particularly for CO 2 fixation reactions. 36,37 This work reports the utilization of diaspore [α-AlO(OH)] as an efficient catalyst for the synthesis of cyclic carbonates from epoxides under ambient CO 2 pressure. Diaspore was prepared through a facile synthetic method, i.e., by reacting Al (NO 3 ) 3 •9H 2 O and urea in water.…”

Structure–Property Relationship in the Lanthanum Grafted Zeolite and Its Application as an Efficient Acido-Basic Catalyst for C–C/C–O Bond Formation Reactions

“…38 Blending of these compounds in fuels improves the fuel properties like viscosity, octane/cetane number, and stability toward oxidation. 39 Moreover, the products of acetalization of glycerol are used as a precursor for the synthesis of important platform chemicals like propanediol and dihydroxyacetone. 40 Another equally important reaction to upgrade the light biomass-derived molecules is aldol condensation of furfural with acetone, wherein the condensation products serve as fuel intermediates.…”

“…The acetalization of glycerol with aldehydes or ketones gives value-added products like dioxane and dioxolane, which are known to be excellent fuel additives, often used as a solvent and a surfactant . Blending of these compounds in fuels improves the fuel properties like viscosity, octane/cetane number, and stability toward oxidation . Moreover, the products of acetalization of glycerol are used as a precursor for the synthesis of important platform chemicals like propanediol and dihydroxyacetone .…”
