NUCLEAR MAGNETIC RESONANCE THE GELLED PRODUCT OF CANNIZZARO REACTION

Abstract

The paper presents the nuclear magnetic resonance (NMR) of proton 1H, carbon 13C and two dimensional spectrums, product of a green organic synthesis of redox on the Cannizzaro reaction. The product was reported as a tribochemical gel (heterogeneous mixture) and confirmed by Infrared Spectroscopy IR, X-ray and scanning electron microscope (SEM). The results in this paper confirm its structure through various techniques of NMR and evaluate the content of sodium benzoate and benzyl alcohol in the spectroscopy sample, examining the values of the integrals on 1H NMR signals. The result of analysis indicates that benzyl alcohol (dispersed phase) is in 33.44% mol in comparison with sodium benzoate content (continuous phase). These results confirm that the gel structure over time loses the dispersed phase of the benzyl alcohol producing a xerogel.
