“…The above results clearly indicated that the importance of the textural and acidic properties to achieve higher yields of the specific target products such as furfural, HMF and levulinic acid. Moreover, as shown below, the nature of calcination temperatures and pore sizes of the metal phosphates, pH, surface phosphate species, and type of surfactants on metal phosphates and carbohydrate sugars along with reaction parameters significantly altered both final target product yields and stability …”

“…Moreover, as compared with zeolites such as Sn-Beta, H-Beta, HY and HZSM-5, the metal phosphates displayed much higher activity and stability for pX production under the same reaction conditions due to their optimal densities of B and L acid sites created on the different metal phosphate species. [86,87,93] In addition, after calcination steps, the used catalysts such as the SnPO, [86] NbOPO 4 [93] and ZrP 1.5 -SBA/ KIT [87] revealed the stable catalytic performances for the production of pX at 250°C.…”

“…The ZrP 1.5 ‐SBA catalyst also effectively catalyzed the furan and 2‐methylfuran into benzene and toluene, although the production rate of pX was found to be very high compared to benzene and toluene under the same reaction conditions.

“…[24,87] However, the best route for sustainable production of BTX with ultra-high selectivity was reported from the biomass-derived furans with gaseous ethylene. [87] For example, a series of mesoporous metal phosphates such as SnPO, [86] NbOPO 4 [93] and ZrP [87] were utilized for tandem Diels-Alder cycloaddition and dehydration reaction for selective production of para-xylene (pX) using 2,5-dimethylfuran (DMF) with gaseous ethylene. A poor DMF conversion of 6.3 % was observed by Kasipandi et al over ZrP nanoparticles that may be owing to a relatively higher DMF concentration of~2.9 M besides the combined effects of relatively lower surface area and acid site concentration.…”

Phosphorus‐modified mesoporous inorganic materials play crucial roles in the valorization of lignocellulosic biomass materials such as syngas (CO and H2), carbohydrate sugars and lignin. This review summarizes the recent advances on the Co‐impregnated phosphorus‐modified γ‐Al2O3 and SiO2 catalysts for production of liquid hydrocarbon fuels via Fischer‐Tropsch synthesis (FTS) reaction of syngas as well as metal phosphates or precious (Pt and Ru) metals‐supported on the metal phosphates for production of furanic compounds, levulinic acid, aromatics and fuel commodities from carbohydrate sugars and lignin. These phosphorus‐modified materials play key roles in the syngas as well as biomass conversion processes due to their tunable surface properties and mesoporous structures. Phosphorus to metal ratios of inorganic materials with their porosity, calcination temperatures of metal phosphates, natures of biomass feedstocks, and reaction variables significantly affect yields of both hydrocarbon fuels and value‐added chemicals. This short review mainly focusses on the various applications of those mesoporous catalysts and supports, and strategies for effective catalytic transformations of lignocellulosic biomass‐derived feedstocks.

Dynamic Trapping as a Selective Route to Renewable Phthalide from Biomass‐Derived Furfuryl Alcohol

et al. 2020

View full text Add to dashboard Cite

A novel route for the production of the versatile chemical building block phthalide from biorenewable furfuryl alcohol and acrylate esters is presented. Two challenges that limit sustainable aromatics production via Diels–Alder (DA) aromatisation—an unfavourable equilibrium position and undesired regioselectivity when using asymmetric addends—were addressed using a dynamic kinetic trapping strategy. Activated acrylates were used to speed up the forward and reverse DA reactions, allowing for one of the four DA adducts to undergo a selective intramolecular lactonisation reaction in the presence of a weak base. The adduct is removed from the equilibrium pool, pulling the system completely to the product with a fixed, desired regiochemistry. A single 1,2‐regioisomeric lactone product was formed in up to 86 % yield and the acrylate activating agent liberated for reuse. The lactone was aromatised to give phthalide in almost quantitative yield in the presence of Ac2O and a catalytic amount of strong acid, or in 79 % using only catalytic acid.

The heterogeneous metal‐organic framework Bi‐BTC successfully catalyzed the synthesis of para‐xylene from bio‐based 2,5‐dimethylfuran and acrylic acid in a promising yield (92 %), under relatively mild conditions (160 °C, 10 bar), and with a low reaction‐energy barrier (47.3 kJ mol−1). The proposed reaction strategy also demonstrates a remarkable versatility for furan derivatives such as furan and 2‐methylfuran.
