Kinetics of Levoglucosenone Isomerization

Title: Kinetics of Levoglucosenone Isomerization

Abstract

In this paper, we studied the acid-catalyzed isomerization of levoglucosenone (LGO) to 5-hydroxymethylfurfural (HMF) and developed a reaction kinetics model that describes the experimental data across a range of conditions (100–150 °C, 50–100 mm H ₂SO ₄, 50–150 mm LGO). LGO and its hydrated derivative exist in equilibrium under these reaction conditions. Thermal and catalytic degradation of HMF are the major sources of carbon loss. Within the range of conditions studied, higher temperatures and shorter reaction times favor the production of HMF. The yields of HMF and levulinic acid decrease monotonically as tetrahydrofuran is added to the aqueous solvent system, indicating that water plays a role in the LGO isomerization reaction. Initial-rate analyses show that HMF is produced solely from LGO rather than from the hydrated derivative of LGO. Finally, the results of this study are consistent with a mechanism for LGO isomerization that proceeds through hydration of the anhydro bridge, followed by ring rearrangement analogous to the isomerization of glucose to fructose.

Production of levoglucosenone and 5-hydroxymethylfurfural from cellulose in polar aprotic solvent–water mixtures

Journal Article He, Jiayue ; Liu, Mingjie ; Huang, Kefeng ; ... - Green Chemistry

In this paper, we demonstrate a process to produce levoglucosenone (LGO) and 5-hydroxymethylfurfural (HMF) from cellulose in up to 65% carbon yield using sulfuric acid as catalyst and a solvent consisting of a mixture of tetrahydrofuran (THF) with water. In pure THF, LGO is the major product of cellulose dehydration, passing through levoglucosan as an intermediate. Increasing the water content (up to 5 wt%) results in HMF as the major product. HMF is formed both by glucose dehydration and direct dehydration of LGA. The maximum combined yield of LGO and HMF (~65 carbon%) is achieved in the presence of 1–2.5more »« less

New catalytic strategies for α,ω-diols production from lignocellulosic biomass

Journal Article He, Jiayue ; Huang, Kefeng ; Barnett, Kevin J. ; ... - Faraday Discussions

Catalytic strategies for the synthesis of 1,5-pentanediol (PDO) with 69% yield from hemicellulose and the synthesis of 1,6-hexanediol (HDO) with 28% yield from cellulose are presented. Fractionation of lignocellulosic biomass (white birch wood chips) in gamma-valerolactone (GVL)/H ₂O generates a pure cellulose solid and a liquid stream containing hemicellulose and lignin, which is further dehydrated to furfural with 85% yield. Furfural is converted to PDO with sequential dehydration, hydration, ring-opening tautomerization, and hydrogenation reactions. Acid-catalyzed cellulose dehydration in tetrahydrofuran (THF)/H ₂O produces a mixture of levoglucosenone (LGO) and 5-hydroxymethylfurfural (HMF), which are converted with hydrogen to tetrahydrofuran-dimethanol (THFDM). HDO ismore »« less

Hydrogenation of levoglucosenone to renewable chemicals

Journal Article Krishna, Siddarth H. ; McClelland, Daniel J. ; Rashke, Quinn A. ; ... - Green Chemistry

Here, we have studied the hydrogenation of levoglucosenone (LGO) to dihydrolevoglucosenone (Cyrene), levoglucosanol (Lgol), and tetrahydrofurandimethanol (THFDM) and elucidated the reaction network over supported palladium catalysts. At low temperature (40 °C) over a Pd/Al ₂O ₃ catalyst, LGO is selectively hydrogenated to Cyrene. At intermediate temperatures (100 °C) over a Pd/Al ₂O ₃ catalyst, Cyrene is selectively hydrogenated to Lgol, with an excess of the exo-Lgol isomer produced over the endo-Lgol isomer. At higher temperatures (150 °C) over a bifunctional Pd/SiO ₂–Al ₂O ₃ catalyst, Lgol is converted to THFDM in 58% selectivity, with 78% overall selectivity to 1,6-hexanediol precursors.more »« less

An in Situ NMR Study of the Mechanism for the Catalytic Conversion of Fructose to 5-Hydroxymethylfurfural and then to Levulinic Acid Using ¹³ C Labeled d -Fructose

Journal Article Zhang, Jing ; Weitz, Eric - ACS Catalysis

The pathways for the formation of 5-hydroxymethylfurfural (HMF) by dehydration of d-fructose and for the formation of levulinic acid and formic acid from HMF by rehydration were investigated by in situ13C and 1H NMR using both unlabeled and 13C-labeled fructose. Water or DMSO was used as the solvent with Amberlyst 70, PO43–/niobic acid, or sulfuric acid as catalysts. Only HMF is observed using NMR for fructose dehydration in DMSO with any of the three catalysts or without a catalyst. For each system, results with 13C-labeled fructose indicate that the first carbon (C-1) or sixth carbon (C-6) of fructose maps ontomore »« less

Tin-containing zeolites are highly active catalysts for the isomerization of glucose in water

Journal Article Moliner, Manuel ; Roman-Leshkov, Yuriy ; Davis, Mark E. - Proc. Natl. Acad. Sci. U. S. A.

The isomerization of glucose into fructose is a large-scale reaction for the production of high-fructose corn syrup (HFCS; reaction performed by enzyme catalysts) and recently is being considered as an intermediate step in the possible route of biomass to fuels and chemicals. Here, it is shown that a large-pore zeolite that contains tin (Sn-Beta) is able to isomerize glucose to fructose in aqueous media with high activity and selectivity. Specifically, a 10% (wt/wt) glucose solution containing a catalytic amount of Sn-Beta (1:50 Sn:glucose molar ratio) gives product yields of approximately 46% (wt/wt) glucose, 31% (wt/wt) fructose, and 9% (wt/wt) mannosemore »« less
