Zainol, Muzakkir Mohammad published the artcileSynthesis and characterization of porous microspherical ionic liquid carbon cryogel catalyst for ethyl levulinate production, SDS of cas: 539-88-8, the main research area is porous microspherical ionic liquid carbon cryogel catalyst ethyl levulinate.
A new type of carbon cryogel was synthesized from ionic liquid, a green solvent, and furfural mixtures Initially, the gel, formed via sol-gel polycondensation reaction, was freeze-dried, calcined and denoted as CCIL. The effect of furfural to IL (F/IL) ratio, water to IL (W/IL) ratio and sulfuric acid loading on the synthesis of gel was investigated. In addition, the effect of calcination temperature and time were also studied for CCIL preparation The phys. and chem. properties were evaluated with nitrogen physisorption, temperature programmed desorption of ammonia (NH3-TPD), and thermogravimetric analyzer (TGA). Fourier transform IR spectroscopy (FTIR), X-ray diffraction (XRD), field emission SEM with energy dispersive X-ray spectrometry (FESEM-EDX), CHNS anal., total organic carbon (TOC) and NMR spectroscopy (NMR) results were also analyzed. Catalytic testing, conducted to evaluate the performance of CCIL in esterification of levulinic acid with ethanol, inferred large total surface area and high acidity corroborated with good activity. The selected CCIL registered Et levulinate yield of 66.9 mol%. The exptl. results demonstrated the catalyst, derived from new feedstocks, is a potential solid acid catalyst for biomass conversion.
Diamond and Related Materials published new progress about Acidity. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, SDS of cas: 539-88-8.
