  High-yielding method for chemical hydrolysis of lignocellulose into monosaccharides. The process of the invention can additionally be applied to cellulose, xylan and related biomass polysaccharides, such as galactan, mannan, or arabinan. The method is employed for hydrolysis of a biomass polysaccharide substrate. The process is carried out in an ionic liquid in which cellulose is soluble in the presence of catalytic acid at a temperature sufficiently high to initiate hydrolysis. Water is added to the reaction mixture after initiation of hydrolysis at a rate controlled to avoid precipitation yet avoid undesired sugar dehydration products such ad HMF. Hydrolysis product is useful as feedstock for fermentations including fermentation processes for ethanol, butanol and other fuels.

  高产的化学水解木质纤维素为单糖的方法。该发明的方法还可以应用于纤维素，木聚糖和相关的生物质多糖，如半乳糖，甘露糖或阿拉伯糖。该方法用于水解生物质多糖底物。该过程在离子液体中进行，其中纤维素在催化酸的存在下溶解，在足够高的温度下启动水解。在水解开始后，将水以控制速率加入反应混合物，以避免沉淀，但避免不希望的糖脱水产物如HMF。水解产物可用作发酵的原料，包括乙醇，丁醇和其他燃料的发酵过程。

  The present disclosure relates to thermal conversion of ketoacids, including methods for increasing the molecular weight of ketoacids, the method including the steps of providing in a reactor a feedstock comprising at least one ketoacid. The feedstock is then subjected to one or more C-C-coupling reaction(s) by heating the feedstock to temperature of 200-500° C. in the absence of a catalyst.
