Integrated conversion and stepwise extraction of whole components in biomass with biphasic system are introduced for producing chems.: levulinates and phenolics. When methanol/dimethoxymethane as biphasic solvent, 46.51% Me levulinate and 18.78% phenolics were obtained with a conversion of 80.59 wt% per 4 g rice straw under the mild reaction conditions. Levulinates were collected with a 87.5 wt% high purity of Me levulinate with stepwise precipitation and extraction from the cellulose and hemicellulose. The results of acid value, f.p., induction period, kinematic viscosity, and flash point supposed that the extracted Me levulinate could meet the requirements of fuel additives. Depolymerized lignin was consisted of many low-mol. phenolics. These results illustrated that the biphasic system can promote the conversion of cellulose and hemicellulose to the same product Me levulinate through different intermediate transition compounds, and the catalyst can contribute to directly cleave the glycosidic bonds, β-O-4, and 4-O-5 with adequate protons. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1COA of Formula: 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. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.COA of Formula: C9H12O3
