Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Résumé

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt, NH4F, has a crucial effect on their morphologies, therefore, their textural and catalytic properties have been mostly influenced. The resulting materials were characterized by X-ray Diffraction (XRD), N2 sorption, Scanning Electron Microscopy (SEM) .The both composites have been successfully used as catalysts for the N-formylation reaction of aniline. As a result, N-phenylformamide was obtained with up to 90 % yield and 100 % selectivity at 50 °C in 4 h (solvent-free conditions) .The catalytic tests were monitored by gas chromatography (GC) and the nature of the products was confirmed by NMR.
