    • The invention relates to a process for preparing furan-2,5-dicarboxylic acid comprising the following steps: (a) preparing or providing a starting material mixture comprising 5-(hydroxymethyl)furfural (HMF) as a first reactant and one or more second reactants selected from the group consisting of esters of 5-(hydroxymethyl)furfural and ethers of 5-(hydroxymethyl)furfural, (b) subjecting said starting material mixture to first oxidation conditions at a temperature in the range TR1 of from 110 to 140 °C so that an amount of said 5-(hydroxymethyl)furfural (HMF) present in the starting material mixture is oxidised to furan-2,5-dicarboxylic acid and a first product mixture results comprising furan-2,5-dicarboxylic acid and an unreacted amount of said one or more second reactants, and (c) subjecting the first product mixture obtained in step (b) or a mixture obtained from the first product mixture obtained in step (b) by additional treatment steps to second oxidation conditions at an increased temperature in the range TR2 of from above 140 to 200 °C so that said at least a fraction of said unreacted amount of said one or more second reactants present in the first product mixture is oxidised and a second product mixture results comprising furan-2,5-dicarboxylic acid.
    • 本发明涉及一种制备呋喃-2,5-二羧酸的方法,其包括以下步骤:(a)制备或提供包含5-(羟甲基)糠醛(HMF)的原料混合物,其为 第一反应物和一种或多种选自5-(羟甲基)糠醛的酯和5-(羟甲基)糠醛的醚的第二反应物,(b)使所述起始原料混合物在第 范围TR1为110-140℃,使得存在于原料混合物中的所述5-(羟甲基)糠醛(HMF)的量被氧化成呋喃-2,5-二羧酸,并且得到包含呋喃的第一产物混合物 (c)将步骤(b)中获得的第一产物混合物或步骤(b)中获得的第一产物混合物获得的混合物用 对第二氧化条件的附加处理步骤 离子在高于140-200℃的范围TR2的升高温度下反应,使得存在于第一产物混合物中的所述至少一部分所述未反应量的所述一种或多种第二反应物被氧化,并且第二产物混合物得到 包含呋喃-2,5-二羧酸。
