Özet

In the study, it is aimed to use effective zeolite-based catalysts for the synthesis of hydroxymethylfurfural (HMF) from starch in different solvent environments. Al, Zn, and heteropolyacid (HPW) loaded USY zeolites are prepared and characterized using XRD, BET method, Inductive Coupling Plasma Mass Spectrometry (ICP-MS), Pyridine-DRIFTS, and X-ray Photoelectron Spectroscopy (XPS). The efficiency of the prepared catalysts is investigated in 1-Butyl-3-Methylimidazolium Chloride (BMIMCI) ionic liquid, DMSO, and THF solvents at different temperatures and reaction times for HMF synthesis. 24.5% HMF yield using Zn-USY zeolite and 50.3% HMF yield using USY H-zeolite is obtained in BMIMCI ionic liquid at 130 degrees C for 3 h. HMF yield of 47% is obtained using Zn-USY zeolite catalyst at 160 degrees C in 4 h, at 170 degrees C in 2 h, and at 180 degrees C in 1 h in DMSO. In a two-phase reaction medium with THF and H2O, the HMF yield is 46.8% at 160 degrees C in 4 h, 52.2% at 170 degrees C in 30 min, and 38.1% at 180 degrees C in 2 h with Zn-USY zeolite catalyst. The reusability of the Zn-USY zeolite has been tested and the efficiency of catalyst does not decrease in reuse for five times.
