Abstract:

The paper aims to elaborate a methodology for establishing the structure and sterical configuration of reduction products with the system Ni-Al/NaOH/H2O by using spectroscopic methods (mainly 1H-NMR) and method of coupling gas chromatography with mass spectrometry (GC-MS). In case of benzoin, the compositional analysis for reduction products was made by gas chromatographic methods (GC) with FID detection. The quantitative analysis was based on the value of integrals of the relevant signals in the 1H-NMR spectrum of the crude reaction product. The 13C-NMR and FTIR spectra provided the necessary information to confirm the quality of the composition of the reaction product.

Keywords:

benzoin, Ni-Al alloy, selective reduction reaction.
