Sustaining the Transition from a Petrobased to a Biobased Chemical Industry with Flow Chemistry

In the current context of transitioning to more sustainable chemical processes, the upgrading of biobased platform molecules (i.e., the chemical transformation of widely available low molecular weight entities from biomass) is attracting significant attention, in particular when combined with enabling continuous flow conditions. The success of this combination is largely due to the ability to explore new process conditions and the perspective of facilitating seamless scalability while maintaining a small overall footprint. This review considers representative continuous flow processes which utilize a selection of currently popular platform molecules that target industrially relevant building blocks, including (a) commodity chemicals, (b) specialty and fine chemicals, and (c) fuels and fuel additives.

Synthesis of hydroxymethylfurfural from cellulose using green processes: A promising biochemical and biofuel feedstock

Inedible, lignocellulosic biomass has been recognized as most promising renewable resource for the production of high value bio-chemicals. The pretreated biomass or isolated cellulose is a biopolymer of glucose used as a stating material for the synthesis of 5-hydroxymethylfurfural (HMF). HMF is listed among the top 10 bio-based chemicals by USA Department of Energy and it acts as feedstock for deriving a number of commodity products (Bonzell and Petersen, 2010, Green Chem. 12, 539). In present review, we have systematically summarized the catalytic reaction for the synthesis of HMF from pretreated biomass/isolated cellulose using green processes. Further, through catalytic approach, HMF is translated into industrial important chemicals (2,5-diformylfuran, furan-2,5-dicarboxylicacid, 2,5-furandimethanol, furfuraylalcohol, etc) or high calorific value biofuel (2,5-dimethylfuran, 2,5-dimethyltetrahydrofuran, 2,5-bis(alkoxymethyl)furans, etc). In the profitable scale of HMF production, levulinic acid (LA) is generated as a major byproduct. Besides HMF, this review also outlines the catalytic strategy for the conversion of LA to industrially important chemicals along with the biofuel additives. Finally, the bio-toxicity of synthesized chemicals, which connected into different functional groups have been summarized to meet the criteria of the green technology for commercialization.

CONVERSION OF CARBOHYDRATES TO HYDROXYMETHYLFURFURAL (HMF) AND DERIVATIVES

A method of producing substantially pure HMF, HMF esters and other derivatives from a carbohydrate source by contacting the carbohydrate source with a solid phase catalyst. A carbohydrate starting material is heated in a solvent in a column and continuously flowed through a solid phase catalyst in the presence of an organic acid, or heated with the organic acid and a solid catalyst in solution to form a HMF ester. Heating without organic acid forms HMF. The resulting product is purified by filtration to remove the unreacted starting materials and catalyst. The HMF ester or a mixture of HMF and HMF ester may then be oxidized to 2,5-furandicarboxylic acid (FDCA) by combining the HMF ester with an organic acid, cobalt acetate, manganese acetate and sodium bromide under pressure. Alternatively, the HMF ester may be reduced to form a furan or tetrahydrofuran diol.

Palladium/carbon dioxide cooperative catalysis for the production of diketone derivatives from carbohydrates

The one-pot production of industrially valuable diketone derivatives from carbohydrates is achieved through a bifunctional catalytic process. In particular, Pd/C-catalyzed hydrogenation of HMF in water and under CO 2 affords 1-hydroxypentane-2,5-dione with up to 77 % yield. The process is also eligible starting from fructose and inulin, affording 1-hydroxyhexane-2,5-dione with 36 % and 15 % yield, respectively. The key of the process is reversible in situ formation of carbonic acid, which is capable of assisting Pd/C during the hydrogenation reaction by promoting the dehydration of carbohydrates and the ring-opening of furanic intermediates. Interestingly, by changing the reaction medium from H2O to a H2O/THF mixture (1:9), it is possible to switch the selectivity of the reaction and to produce 2,5-hexanadione with 83 % yield. Within the framework of sustainable chemistry, reactions presented in this report show 100 % carbon economy, involve CO 2 to generate acidity, require water as a solvent, and are conducted under rather low hydrogen pressures (10 bar).

Mesoporous ZrO2 Nanopowder Catalysts for the Synthesis of 5-Hydroxymethylfurfural

Balancing the large surface area and high crystallinity of heterogeneous metal oxide catalysts is quite tricky. They are usually needed together to get both a large amount of active catalytic sites and high thermal stability. In this paper, the preparation of porous sulfate ZrO2 as solid acid catalysts is reported. The monolithic porous SiO2 created confined spaces in which porous ZrO2 was synthesized in it. The ZrO2 has excellent porous structure in which the specific surface area reaches 277 m2 g-1 and has good crystallinity. At the same time, they have high acid site loading (2.57 mmol g-1) upon sulfation. The sulfonic ZrO2 exhibits excellent catalytic performance when considering the dehydration of 5-HMF from d-fructose. The yield of 5-HMF is 87% for 60 min at 120 C. Thus, this solid acid catalyst was a potential candidate for heterogeneous catalysis and biomass quick conversion.

Catalytic selective hydrogenation and rearrangement of 5-hydroxymethylfurfural to 3-hydroxymethyl-cyclopentone over a bimetallic nickel-copper catalyst in water

The selective hydrogenation and rearrangement of 5-hydroxymethylfurfural (5-HMF) to 3-hydroxymethyl-cyclopentone (HCPN) were studied over a MOF-derived bimetallic nickel-copper catalyst in water. The combination of nickel and copper dramatically improved the efficiency in both the selective hydrogenation of the carbonyl group of 5-HMF and the hydrogenative ring-rearrangement of the C5 ring, affording 70.3% yield for HCPN and 99.8% yield for the rearrangement products. Moreover, it was indicated that water acted as a solvent, reactant, and proton donor by dissociation at an elevated temperature, which supplied slightly acidic conditions and promoted the rearrangement reaction.

Efficient hydrogenolysis of 5-hydroxymethylfurfural to 2,5-dimethylfuran over a cobalt and copper bimetallic catalyst on N-graphene-modified Al2O3

2,5-Dimethylfuran (DMF) is an important candidate for liquid fuels and can be produced from biomass derived 5-hydroxymethylfurfural (HMF). Efficient transformation of HMF to DMF has not been achieved over a non-noble catalyst under milder conditions. Herein, we developed a copper and cobalt bimetallic nanoparticle catalyst supported on N-graphene-modified Al2O3 (CuCo/NGr/alpha-Al2O3). It was found that CuCo/NGr/alpha-Al2O3 could catalyze the conversion of HMF to DMF effectively and the yield of DMF could reach 99%. The catalyst was completely not active for the hydrogenation of the C=C bond in furan and thus no 2,5-bis(hydroxymethyl)tetrahydrofuran (DHTHF) and 2,5-dimethyltetrahydrofuran (DMTHF) were detected.
