Directional microwave-assisted liquefaction and stepwise extraction are introduced for producing platform chemicals: aromatics and monosaccharides. When sulfuric acid was used as a catalyst, a 45% monosaccharides yield and a 29% aromatics yield were obtained from bamboo with 0.3g catalyst per 18g methanol and 2g bamboo at 160°C with 10min. Approximately 78-86wt% of the six biomass materials were converted into liquid products. After the stepwise extraction and precipitation process, the yields of monosaccharide derivatives and three phenolic compound fractions were 39-45% and 28-32%, respectively. Monosaccharides from holocellulose collected with a high purity of methyl glycosides were higher than 90%. Aromatic derivatives with different weight-molecular distributions were separated into three fractions with more than 80% phenolics. As their similar chemical properties within each fraction, platform chemicals have great commercial potential for producing high-quality chemicals and biofuels using mild upgrading conditions.
芳烃和单糖。当硫酸用作催化剂时，在 160°C 下，每 18g 甲醇和 2g 竹子使用 0.3g 催化剂，可从竹子中获得 45%的单糖收率和 29%的芳烃收率。大约 78-86wt%的六种生物质材料被转化为液体产品。经过分步提取和沉淀过程，单糖衍生物和三种酚类化合物级分的产率分别为 39-45%和 28-32%。用高纯度甲苷收集的全纤维素中单糖的纯度高于 90%。具有不同重量-分子量分布的芳烃衍生物被分离成三个酚类含量超过 80%的级分。由于它们在每个级分内具有相似的化学性质，因此这些平台化学品在使用温和的升级条件生产高质量化学品和生物燃料方面具有巨大的商业潜力。
