The complete conversion of hemicellulose, cellulose and lignin in lignocellulosic biomass into value-added chemicals is of great significance in biorefinery processes. Herein, a cascade-step strategy was developed for the conversion of hemicellulose and lignin into mixed organic acids, and cellulose into ethylene glycol. Typical biomass of Miscanthus was first treated with formic acid in the presence of H2O2, giving a formic acid solution and cellulosic biomass. Lignin in Miscanthus was oxidized to low polymerized organic acids through linkage cleavages and aromatic ring ruptures during the treatment process, forming a homogeneous formic acid solution with a weight yield of 95%. Hemicellulose was transformed into maleic acid at 56.2% selectivity via a hydrolysis-dehydration-oxidation process. Both hemicellulose and lignin were degraded into organic acids with an overall weight yield of 92.4%. The cellulose in the solid residue had a hydrophilic surface and is highly accessible to catalysts in the aqueous solution, and it was totally converted into ethylene glycol with a yield of up to 65.7% over a binary catalyst of H2WO4-Ru/C. Relying on such a cascade reaction strategy, the three major components of Miscanthus were transformed into mixed organic acids and ethylene glycol, which provides a potential strategy for complete valorisation of biomass into value-added chemicals.

I found the field of Engineering very interesting.

Formula: C5H10O4, Reprint Addresses Li, XH (corresponding author), South China Univ Technol, State Key Lab Pulp & Paper Engn, Sch Chem & Chem Engn, Guangzhou 510640, Peoples R China..

Catalytic conversion of lignin to versatile aromatic compounds is attracting increasing attention. However, it is highly desirable but challenging to produce a specific chemical with high yield through lignin depolymerization in a one-pot process because of the complex structure of the lignin molecule (mainly composed of H, G, and S units). In this study, a series of metal-based deep eutectic solvents (M-DESs) were prepared and used for the catalytic tailoring of lignin H units to produce value-added methyl p-hydroxycinnamate (MPC). In particular, M-DES ChCl[FeCl3](2) showed excellent catalytic performance for the selective production of MPC as the sole product with high yield and selectivity (105.8 mg g(-1) and 74.1%, respectively). Extensive characterizations using 2D HSQC NMR, C-13 NMR, and GPC demonstrated that MPC was obtained from the selective tailoring of p-coumaric acid (pCA) units via the cleavage of ester bonds in lignin. Furthermore, M-DES ChCl[FeCl3](2) also exhibited efficiency to other herbaceous lignins, and showed excellent recyclability. Therefore, this work provides an effective strategy for the valorization of lignin.

Comprehension in hemicellulose pyrolysis is critical to generate renewable fuel and valuable chemical. Herein, a self-designed tubular reactor was applied to observe the appearance alteration and chemical structure evolution during the whole xylan pyrolysis process. Before 200 degrees C, it was free moisture removal stage without significant chemical structure alteration. Xylan began to depolymerize at 200 degrees C corresponding with the appearance change from its original state to dark brown, cleavage of branched-chain and primary product acids & ketones generation. The main chain of xylan was completely broken at 250-350 degrees C via beta-1,4-glycosidic bond cleavage, dehydration, decarboxylation, and decarbonylation reaction. Acids were mainly originated from hemicellulose pyrolysis. The typical signals from FTIR,C-13 CP/MAS NMR were disappeared at 350 degrees C. In the carbonation stage, the C/H and C/O ratio reached 2.01 and 4.54, leading to the aromaticity enhancement of char and formation of carbon-centered radicals.

I found the field of Science & Technology – Other Topics very interesting. Saw the article Concise asymmetric synthesis of (-)-bilobalide published in 2019.

The Ginkgo biloba metabolite bilobalide is widely ingested by humans but its effect on the mammalian central nervous system is not fully understood(1-4). Antagonism of gamma-aminobutyric acid A receptors (GABA(A)Rs) by bilobalide has been linked to the rescue of cognitive deficits in mouse models of Down syndrome(5). A lack of convulsant activity coupled with neuroprotective effects have led some to postulate an alternative, unidentified target(4); however, steric congestion and the instability of bilobalide(1,2,6) have prevented pull-down of biological targets other than the GABA(A)Rs. A concise and flexible synthesis of bilobalide would facilitate the development of probes for the identification of potential new targets, analogues with differential selectivity between insect and human GABA(A)Rs, and stabilized analogues with an enhanced serum half-life(7). Here we exploit the unusual reactivity of bilobalide to enable a late-stage deep oxidation that symmetrizes the molecular core and enables oxidation states to be embedded in the starting materials. The same overall strategy may be applicable to G. biloba congeners, including the ginkgolides-some of which are glycine-receptor-selective antagonists(8). A chemical synthesis of bilobalide should facilitate the investigation of its biological effects and its therapeutic potential.
