Resumen

The benzaldehyde acetalization reaction catalyzed by UiO-66, and its fluorinated analog UiO-66F, was carried out in a batch-type reactor at room temperature and atmospheric pressure, and the full kinetic study was performed using the Langmuir-Hinshelwood and Eley-Rideal models. It was established that the Eley-Rideal model is the one that best fits the experimental data. The catalytic results indicated that both MOFs enable carrying out the acetalization reaction. However, UiO-66F has the highest activity, which could be attributed to its high acidity. Both structures were characterized by N2physisorption, thermogravimetry, powder X-ray diffraction, potentiometric titrations, and infrared spectroscopy. The highest acidity displayed by UiO-66F was explained by DFT studies and experimental studies.
