The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Methylfuran-2(3H)-one(SMILESS: O=C1OC(C)=CC1,cas:591-12-8) is researched.Related Products of 591-12-8. The article 《Humins with Efficient Electromagnetic Wave Absorption: A By-Product of Furfural Conversion to Isopropyl Levulinate via a Tandem Catalytic Reaction in One-Pot》 in relation to this compound, is published in Chemistry – A European Journal. Let’s take a look at the latest research on this compound (cas:591-12-8).
Both one-pot catalytic conversion of furfural (FAL) to iso-Pr levulinate (PL) and carbonization of byproduct (humins) for electromagnetic wave absorption are discussed, which provides inspiration that humins can be applied to electromagnetic wave absorption. In the former, phosphotungstic acid (PW) is employed as a homogeneous catalyst to convert FAL to PL via a tandem reaction in one pot, with the formation of a vast amount of humins. With FAL and various intermediates as substrates, it was found that humins was a polymerization product of FAL, furfuryl alc. (FOL) and furfuryl ester (FE) with furan rings. In addition, the in situ attenuated total reflection IR (ATR-IR) spectra also provided a basis for the proposed reaction route. In the latter, with the humins as raw material, P species and WO3 doped nano-porous carbon (Humins-700) platform formed after high-temperature annealing is used for electromagnetic wave absorption and manifests desirable absorption performance. The min. reflection loss (RLmin) value is -47.3 dB at 13.0 GHz with a thickness of 2.0 mm and the effective absorption bandwidth reaches 4.5 GHz (11.2-5.7 GHz).
