An effective method for the cleavage of the C-O bonds in lignin α-O-4 dimers and various alk. lignins including the lignin from pulp industry was developed over a heterogeneous ReOx/AC catalyst. High yield of aromatic monomers (up to 98.0%) from α-O-4 model compounds and up to 80.1% lignin oil with 24.5% yield of monomers from realistic lignin were obtained under optimized conditions. Alk. poplar lignin provided syringylpropane and 4-propenylsyringol with the highest yield of 6.6% and 7.4%, resp. The active sites of ReOx/AC could be assigned to ReIV-VI according to XPS and EXAFS characterization. The lignin structures of different botanical species (hardwood, softwood and herbaceous crop) were compared and the activity of ReOx/AC on these lignins was studied in detail. GPC and 2D HSQC NMR anal. of isolated lignin and lignin oil showed that hardwood lignin was more liable to be deconstructed than softwood and grass lignins due to the less amounts of β-5 linkages, lower mol. weight and richer syringyl (S) units in hardwood lignin. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Related Products of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 103-16-2
