Alkaline niobates ANbO3 (A = Li, Na, K) as heterogeneous catalysts for dipropyl sulfide oxidation

Candelaria Leal Marchena; Clara Saux; Robinson Dinamarca; Gina Pecchi; Liliana Beatriz Pierella

Alkaline ANbO3 (A = Li, Na, K) niobates with perovskite-type structure were prepared by a sol gel method, characterized by XRD, BET, TG/DTA, O2-TPD, DRS UV-Vis and FTIR and evaluated as heterogeneous catalysts for the selective oxidation of dipropyl sulfide (DPS) to its corresponding sulfoxide. The effects of different reaction parameters were evaluated, such as catalyst weight, the solvent and oxidant nature, reaction temperature and reuse. In order to gain better knowledge of the oxidation process, a kinetic study of the reaction was carried out. The global pseudo first order constant, the initial reaction rate and the apparent activation energy were calculated, and simplified reaction steps are proposed. KNbO3 showed the highest catalytic activity and sulfoxide selectivity with a periodic trend of KNbO3 > NaNbO3 ∼ LiNbO3.

Abstract Intensification process by the use of microwave heating was investigated by testing two catalyst configurations on the selective styrene oxidation for benzaldehyde production. The oxidation reaction was studied over Co-ZSM-11 and Fe-ZSM-11 catalysts. Their catalytic activity was evaluated by using these catalysts in two different forms: compacted pellets and fine particles. Thus, two reaction systems were studied under microwave: a batch system with fine particles in suspension (system 1) and a recirculating batch liquid through a fixed bed system comprising the compact catalyst pellets (system 2). Despite a better microwave interaction with the catalyst in the pellet form, the fixed bed configuration did not lead to a significant intensification of the process. At 60°C, the styrene molar conversions by using Co-ZSM-11 catalyst were found to be 33% and 3% for systems 1 and 2, respectively. With fine particles, the catalytic activity was higher since the styrene oxidation was able to occur without significant internal diffusional resistance of the reagents toward the active acid sites of the zeolite structure.
