Aromatic Content Determination of Kerosene by Proton and Carbon Nuclear Magnetic Resonance Spectroscopy

One of the most characteristic parameters of an organic hydrocarbon is aromatic and aliphatic contents determination. Aromaticity content of an organic hydrocarbon can affect on variety of properties such as boiling range, viscosity, stability, heat resistance and compatibility with other materials. Nuclear magnetic resonance spectroscopy (NMR) is the most efficient and effective technique for determination of protons (1H) and carbons (13C) aromatic and aliphatic content in organic hydrocarbons. Presence of hydrogen and carbon atoms in hydrocarbon materials such as, kerosene causes the nuclear magnetic resonance spectroscopy studies to be performable on the atoms. Kerosene is the most known materials in oil industries that it is including wide range organic hydrocarbons. Depends on source of this material, aromatic and aliphatic contents of kerosene can be different. Nuclear magnetic resonance spectroscopy results show that kerosene (for example from Aldrich Co.) has 3.589% aromatic hydrogens and 9.462% aromatic carbons.
