Nanocrystalline Magnesium Oxide as a Versatile Heterogeneous Catalyst for the Meerwein–Ponndorf–Verley Reduction of Cyclohexanone into Cyclohexanol: Effect of Preparation Method of Magnesium Oxide on Yield

Abstract

The Meerwein-Ponndorf-Verley (MPV) reaction of cyclohexanone with 2-propanol in the liquid phase in the presence of two different nanocrystalline magnesium oxides, prepared by different methods, was investigated. The catalyst consisting of nanocrystalline magnesium oxide, which was prepared by calcination of magnesium methoxide in air at 400°C, showed the highest activity in the conversion of cyclohexanone to cyclohexanol with 97% yield. The effect of calcination temperature of magnesium oxide on the cyclohexanol yield and reusability of the catalyst has been studied.

Preparation and Characterization of Mg/TiO2 for Visible Light Photooxidative-Extractive Deep Desulfurization

“…In addition, the photocatalysts also showed impressive recyclability of up to five photocatalytic activity cycles (Feng et al 2013). The applications of magnesium oxide (MgO) nanomaterials are extremely wide extending from areas in catalysis (Carabineiro et al 2011;Ganguly et al 2011;Heidari et al 2009), to superconductivity (Yuan et al 1996). This is due to its unique physical and chemical properties.…”

Optical and fluorescence properties of MgO nanoparticles in micellar solution of hydroxyethyl laurdimonium chloride

“…Magnesium oxide (MgO) is an important functional metal oxide that has been widely used in various fields such as catalysis, refractory materials, paints, and superconductors [3,4]. Nanostructured MgO has high surface area and therefore acts as coating agent which helps in increasing the energy conversion efficiency [5].…”
