摘要

Based on Transcarpathian zeolite the catalysts in calcium-lanthanum-ammonium form were synthesized and modified by steaming and dealumination with ethylenediaminetetraacetic acid. The samples were characterized by using nitrogen adsorption/desorption, XRD, XRF, and FTIR-spectroscopy. The yield of 5 hydroxymethylfurfural over modified samples at 433 K was found to be 50 and 83% at a practically full conversion of fructose.
