In the present study, methanolysis of poplar biomass was conducted for the selective transformation of hemicellulose and lignin, which leads to Me glycosides (mainly C5 glycosides) and lignin fragments in the liquefied products that can be separated according to their difference in hydrophilicity. The distribution of Me glycosides and delignification was dependent on the presence of acid catalysts and reaction temperatures The obtained lignin fraction was separated into solid lignin fragments and liquid lignin oil according to their mol. weight distribution. Subsequently, directional conversion of Me C5 glycosides into Me levulinate was performed with dimethoxymethane/methanol as the cosolvent. A yield of 12-30% of Me levulinate yield (based on the Me glycoside) was achieved under these conditions. The remaining cellulose-rich substrate showed enhanced susceptibility to enzymic hydrolysis, resulting in a yield of glucose of above 70%. Overall, the described strategy shows practical implications for the effective valorization of biomass. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) 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. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Synthetic Route of C9H12O3
