Description
Summary:In the present work, mass spectroscopy (MS) and 1H nuclear magnetic resonance (NMR) spectroscopy methods have been used to determine the total aromatics content in diesel-range products. The data indicate that both the methods exhibit good correlation among each other, although the MS method has a tendency to provide higher aromatic results for the case of samples that contain a greater amount of sulfur. The possible factors responsible for variations in the results from both techniques have been discussed. The reproducibility of the aromatic data is dependent on the intrinsic nature of the technique and the analytical method applied. This systematic comparative study has proved that NMR spectroscopy is a fast and reliable alternative method to MS for estimation of the total aromatics content in diesel-range products.
