Kinetics of Henry reaction catalyzed by fluorapatite

Abstract

Kinetics of Henry reaction was performed to investigate the performance of fluorapatite. (FAP) catalyst. It was found that the catalyst showed the highest conversion and selectivity of 65% and 80%, respectively at 323 K. Kinetic model was validated, and the absence of mass-transfer resistance was proved by the Weisz Prater criterion. The as-synthesized catalyst is characterized using BET nitrogen adsorption-desorption, FTIR, FE-SEM, TPD-CO2, XPS, and XRD. Effect of catalyst loading, temperature, mole-ratio, speed of stirring, and solvents were studied. FAP catalyst showed good reusability up to four cycles.
