So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhang, Zhenwei; Wang, Peng; Wu, Zeying; Yue, Chuanjun; Wei, Xuejiao; Zheng, Jiwei; Xiang, Mei; Liu, Baoliang researched the compound: 5-Methylfuran-2(3H)-one( cas:591-12-8 ).Name: 5-Methylfuran-2(3H)-one.They published the article 《Efficient synthesis of niobium pentoxide nanowires and application in ethanolysis of furfuryl alcohol》 about this compound( cas:591-12-8 ) in RSC Advances. Keywords: niobium pentoxide nanowire furfuryl alc ethanolysis. We’ll tell you more about this compound (cas:591-12-8).
Nb2O5 nanowires with high sp. surface area and crystallinity were prepared by using ammonium oxalate and an acetic acid solvent system. The nanomaterial was applied in ethanolysis of furfuryl alc. (FA), and the yield of the product, 2-(ethoxymethyl)furan (FEE), achieved was up to 79.6%. Compared to mesoporous Nb2O5 materials and other porous materials, the residence time of FEE on the surface of the catalyst is shorter, and the yield of Et levulinate (EL) is lower. Furthermore, a high temperature calcination treatment can change the acid sites and acidity type distribution on the nanowire surface. By XRD, NH3O5 -TPD, IR, and TG-DTA determination methods, it was found that the weak and medium-strong acid sites on the surface of Nb2O5 nanowires were reduced after a 300°C treatment, and the amount of strong acid was relatively higher. According to the catalytic performance test data and acidity determination, it was concluded that more weak acid and medium-strong acid sites improve the conversion of furfuryl alc. to FEE, and the strong acid sites promote further conversion of FEE to EL.
After consulting a lot of data, we found that this compound(591-12-8)Name: 5-Methylfuran-2(3H)-one can be used in many types of reactions. And in most cases, this compound has more advantages.
