Abstract

P-nitrobenzaldehyde used as an intermediate for the production of fine chemicals and pharmaceuticals was synthesized by Cannizzaro reaction by refluxing in DMF solvent where p-nitrobenzaldehyde was converted to p- nitrobenzyl alcohol and p-nitrobenzoic acid by self oxidation-and-reduction.Natrolite was synthesized in the laboratory by hydrothermal method, after calcinations. The sample was characterized by different techniques such as powder X-ray diffraction analysis (XRD) and Fourier Transform Infrared Spectroscopy (FTIR). Effect of various reaction parameters such as reaction time, molar ratio of reactants, and weight of catalyst and reaction temperature were studied to optimize the reaction conditions. The optimum condition for the synthesis of p nitrobenzaldehyde was found at p-nitro benzoic acid, p-nitro benzyl alcohol molar ratio 8:1, using 0.040 g of the catalyst at 800c. The product was analyzed by Gas Chromatography and with FID Detector. The conversion of p- nitrobezaldehyde to p-nitrobenzoic acid and p-nitrobenzyl alcohol was found to be 40.0 % p-NBA) and 10.0% (p-NBOH) form of H-Natrolite zeolite respectively.
