Sahu, Preeti published the artcileZeolite-β based molecular sieves: A potential catalyst for esterification of biomass derived model compound levulinic acid, Application of Ethyl 4-oxopentanoate, the main research area is levulinic acid zeolite mol sieve potential catalyst esterification.
A series of hetero ions (iron, boron, gallium, titanium, and zinc [Fe3+, B3+, Ga3+, Ti4+, and Zn2+, resp.)] incorporated zeolite-β is prepared via a simple hydrothermal method within 48 h at 170°. Fourier transform-IR spectroscopy anal. and powder X-ray diffraction (FT-IR and XRD, resp.) studies demonstrated the formation of the crystalline phase of the zeolite framework with BEA structure. Scanning electron microscope (SEM) images showed a uniform spherical shape with a particle size of <1μm. The presence of strong acidic sites and the microporous nature of the materials was evident from sorption studies. The resulting Al-, Ga-, Zn-, and Ti- containing zeolite-β materials showed excellent activity for the esterification of levulinic acid using several alcs. (such as methanol, n-butanol, and amyl alc.) with a levulinate ester yield of more than 95%. Significant advantages of the protocol include good activity, the use of a green solvent, and easy removal of the catalyst via filtration. The catalyst activity remained almost intact even after several reaction cycles. Materials Science for Energy Technologies published new progress about Biomass. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, Application of Ethyl 4-oxopentanoate.
