Pachamuthu, M. P. published the artcilePreparation of mesoporous stannosilicates SnTUD-1 and catalytic activity in levulinic acid esterification, Synthetic Route of 539-88-8, the main research area is mesoporous stannosilicate SnTUD1 catalytic levulinate esterification.
The direct synthesis of SnTUD-1 with different Si:Sn ratios (100, 50 and 25) by using non-surfactant template triethanolamine (TEA). It functioned as a structure-directing agent and assisted to graft the Sn ions into the TUD-1 silica layer. The physicochem. properties of these materials were examined with XRD, N2 sorption, DR UV-Vis, NH3-TPD, 29Si-NMR, HRTEM, XPS and pyridine adsorbed FT-IR studies, which indicated highly interconnected mesoporous structure with wormhole like morphol. Sn4+ ions were mainly tetrahedrically coordinated with silica; while increase of loading lead to the formation of nanocrystalline SnO2 with different sizes. Materials showed acidity in the range of 0.13-0.31 mmol/g. Synthesized catalysts were tested in the esterification of levulinic acid (LA) with various aliphatic alcs. and exhibited excellent activity. The catalyst was recycled five times without loss of its activity.
Microporous and Mesoporous Materials published new progress about Esterification. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, Synthetic Route of 539-88-8.
