WebEthylene glycol has relatively high mammalian toxicity when ingested, roughly on par with methanol, with an oral LD Lo = 786 mg/kg for humans. The major danger is due to its sweet taste, which can attract children … The lignins obtained upon treatment in various DES systems shown in Table 1 were structurally characterized in terms of linkage distribution, extent of condensation as well as ethylene glycol incorporation. The observation of negligible nitrogen content by elemental analysis confirmed that there is no choline … See more Acid-catalyzed lignin depolymerization generally results in low aromatic monomer yield due to extensive recondensation that occurs under these … See more Lignocellulose fractionation has been extensively studied in binary DES, mainly ChCl/lactic acid15,16 and ChCl/OA DES18 (see also … See more The DP-DES system was extended to using a variety of lignin model compounds as well as a range of diols. First, model compound 1a was treated with previously optimized DP-DES composition (ChCl, 30 mmol: diol, 60 mmol: … See more To show the potential of the developed protection methodology for lignin depolymerization, the DES-treated lignins were subjected to … See more
