The selective conversion of lignin into aromatic compounds has the potential to serve as a “green” alternative to the production of petrochem. aromatics Herein, we evaluate the addition of di-Me carbonate (DMC) to a biomass conversion system that uses a Cu-doped porous metal oxide (Cu20PMO) catalyst in supercritical methanol (s.c.-MeOH) to disassemble lignin with little to no char formation. While Cu20PMO catalyzes C-O hydrogenolysis of aryl-ether bonds linking lignin monomers, it also catalyzes arene methylation and hydrogenation, leading to product proliferation. The MeOH/DMC co-solvent system significantly suppresses arene hydrogenation of the phenolic intermediates responsible for much of the undesirable product diversity via O-methylation of phenolic -OH groups to form more stable aryl-OCH3 species. Consequently, product proliferation was greatly reduced and aromatic yields greatly enhanced with lignin models, 2-methoxy-4-propylphenol, benzyl Ph ether, and 2-phenoxy-1-phenylethan-1-ol. In addition, organosolv poplar lignin (OPL) was examined as a substrate in the MeOH/DMC co-solvent system. The products were characterized by NMR spectroscopy (31P, 13C, and 2D 1H-13C NMR) and gas chromatog-raphy-mass spectrometry techniques. The co-solvent system demonstrated enhanced yields of aromatic products. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Related Products of 3929-47-3).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Related Products of 3929-47-3
