    • A process for removing acetaldehyde efficiently and producing high-purity acetic acid stably is provided. Methanol is allowed to continuously react with carbon monoxide in a carbonylation reactor 1 in the presence of a catalyst system; the reaction mixture is continuously fed to a flasher 2 to form a volatile phase (2A) containing acetic acid and methyl iodide; the volatile phase (2A) is continuously fed to a splitter column 3 to form an overhead (3A) containing methyl iodide and acetaldehyde and a stream (3B) containing acetic acid; the volatile phase (2A) and/or the overhead (3A) is cooled by a first condenser C1, C3 at a predetermined cooling temperature; and the noncondensed gaseous component is further cooled by a second condenser C2, C4 to form a concentrate having a lower temperature and a higher acetaldehyde concentration. Acetaldehyde is efficiently removed by distilling the concentrate having a high acetaldehyde concentration.

    • The invention provides a process for the isolation of levulinic acid and formic acid from a composition comprising formic acid and levulinic acid, said process comprising a solid-liquid separation step, a vapor removal step, and a solvent-solvent extraction step, wherein a vapor condensate vapor and/or an aqueous phase from the solvent extraction is used to wash the solid fraction. Washing with vapor condensate results in higher levulinic acid yields (higher levulinic acid recovery) as compared to washing with normal water. Washing with aqueous phase results in a less compressible filter cake. Washing first with aqueous phase and subsequently with condensate results in even higher levulinic acid yields. The process is suitable for isolating levulinic acid and formic acid from compositions made by acid hydrolysis of a lignocellulosic biomass, and also from compositions made by acid hydrolysis of sugars such as glucose and fructose.
    • 本发明提供了从包含甲酸和乙酰丙酸的组合物中分离乙酰丙酸和甲酸的方法,所述方法包括固液分离步骤,蒸气去除步骤和溶剂 - 溶剂萃取步骤,其中蒸气 使用来自溶剂萃取的冷凝物蒸气和/或水相洗涤固体部分。 与普通水洗涤相比,用蒸气冷凝液洗涤导致更高的乙酰丙酸产量(更高的乙酰丙酸回收率)。 用水相洗涤会导致较不压缩的滤饼。 首先用水相洗涤,随后用冷凝液洗脱得到甚至更高的乙酰丙酸产率。 该方法适合于通过木质纤维素生物质的酸水解制备的组合物以及由糖如葡萄糖和果糖的酸水解制备的组合物分离乙酰丙酸和甲酸。
