Reduction of benzaldehyde on alkaline earth metal oxides

Hydrogenation of Benzaldehyde over Palladium Intercalated Bentonite Catalysts: Kinetic Studies

“…Previous literatures show that benzaldehyde hydrogenation follows first-order rate law; however, the rate equation do not describe the benzaldehyde kinetics satisfactorily [12][13][14] and requires more extensive kinetic model for the reactions [15]. Neri et al studied the effect of temperature using Langmuir Hinshelwood kinetics [16], they found that adsorption of reactant and desorption of product are in equilibrium and surface reaction is the rate controlling step.…”

A study on the catalytic hydrogenation of aldehydes using mayenite as active support for palladium

“…However, the selectivity of many systems is still low due to the tendency of benzyl alcohols to give the corresponding methyl arenes under the reaction conditions commonly used for the hydrogenation [5]. Furthermore, in the case of heterogeneous catalysts, not only the nature of the metal but also the choice of an appropriate support upon which to disperse a metal can have a relevant effect on both the activity and selectivity [6]. As a matter of fact a large variety of support have been used for palladium catalyzed hydrogenation of benzaldehyde comprising Al 2 O 3 [7], SiO 2 [8], carbon nanotubes [9], and bentonite [10].…”

Benzaldehyde reduction over Cu–Al–O bimetallic oxide catalyst. Influence of pH during hydrothermal synthesis on the structural and catalytic properties

“…Nowadays, most heterogeneous catalysts are based on transition metals [4][5][6], alkaline-earth oxide and layered double hydroxides [7,8]. Systems involving supported noble metals and other supported metal oxides have been also reported [4,7].…”
