Abstract :
HMCM-22 with a Si:Al molar ratio of 15:1 has been shown to effectively catalyze the synthesis of acetals with 100%
selectivity by the reaction of aldehydes with methanol under reflux conditions. Platelet HMCM-22 particles were prepared by
the static strategy and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform
infrared spectroscopy (FT-IR), BET techniques and N2-adsorption/desorption analysis. The catalyst was recovered by simple
filtration and reused for several cycles without considerable loss of activity.
