Titanium silicate molecular sieve (TS-1) and acetic acid efficiently catalyze the oxidation of furan and furan derivatives to the corresponding maleic acid (MA) in very good yields using hydrogen peroxide as an oxidizing agent. The effect of various solvents, the effect of temperature, reaction time, concentration of hydrogen peroxide, and quantities of the catalyst on the MA yield was studied. With the best conditions, MA is the sole product obtained after a fast and simple purification by filtration and evaporation. Compared to the previously reported methods, this work is a good compromise between the different reaction parameters and offers a good alternative to the production of biosourced MA.

在基于乙酸和TS-1和过氧化氢的简单催化剂体系的存在下，糠醛和呋喃衍生物被氧化为马来酸。

使用过氧化氢作为氧化剂，硅酸钛分子筛（TS-1）和乙酸可有效地催化呋喃和呋喃衍生物氧化为相应的马来酸（MA）。研究了各种溶剂，温度，反应时间，过氧化氢浓度和催化剂用量对MA收率的影响。在最佳条件下，MA是通过过滤和蒸发快速简单纯化后获得的唯一产品。与以前报道的方法相比，这项工作很好地折衷了不同的反应参数，并为生产生物来源的MA提供了很好的选择。
