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.Safety of 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride. The article 《Niobium based macromolecule preparation and its potential application in biomass derived levulinic acid esterification》 in relation to this compound, is published in Inorganic Chemistry Communications. Let’s take a look at the latest research on this compound (cas:591-12-8).
Niobium incorporated meso-tetra-(4-carboxyphenyl)-porphyrin (Nb-TCPP) was prepared for the first time and grafted through the axial position by the surface amine groups present on functionalized SBA-15 (SBA-AM). The synthesized TCPP ligand, Nb-TCPP complex, and the grafted Nb-TCPP-SBA-AM complex were thoroughly characterized by various anal. and spectroscopic techniques such as FTIR, UV-visible, DR UV-visible, CHN, 1H NMR, powder XRD, and N2 sorption studies. The catalytic activity of the homogeneous (Nb-TCPP) and the heterogenized (Nb-TCPP-SBA-AM) complex were explored for the esterification of levulinic acid. The studies revealed that Nb-TCPP and Nb-TCPP-SBA-AM showed comparatively good catalytic activity (74-80% conversion) for the esterification of levulinic acid using methanol under mild reaction conditions with the formation of Me levulinate and α-angelica lactone as the major products.
