Anjali, Kaiprathu published the artcileNiobium based macromolecule preparation and its potential application in biomass derived levulinic acid esterification, Application In Synthesis of 539-88-8, the main research area is preparation niobium carboxyphenylporphyrin complex levulinate esterification; levulinate esterification niobium carboxyphenylporphyrin complex catalyst; niobium macromol biomass levulinate esterification.
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.
