| Popis: | The characterization of thermal degradation process of synthetic lubricating oils in relation to its spectroscopic properties was evaluated in this work. The fundamental key to understanding synthetic lubricating oxidation is having basic knowledge of the chemistry of lubricants and their degradation. Synthetic lubricants were degraded at different temperatures and times, under air atmosphere. After thermal degradation, lubricant oils were characterized by infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR) and gas chromatographic/mass spectrometry (GC/MS). IR, NMR, and GC/MS spectra indicated oxidation reaction products. |
