Synthesis Of Oreganic Molybedenum And Exploration Of New Methods Of Oxidative Stability

Phosphorus in the engine oil is harmful to the catalytic converter and the Sulfur oxides causes air pollution. So reducing the content of sulfur and phosphorus is the development direction of antioxidants. New method of oxidative stability of antioxidants was investigated. The simulation of oxidation with Fenton's reagent was determined. The reasonableness of Fenton's reagent simulations was verified by infrared spectroscopy, visible spectrometry and thin layer chromatography. Carbonyl peak index was measured by FT-IR. Meanwhile, this study also aimed to develop non-sulfur, non-phosphorus organic Molybdenum antioxidants, explored by a fatty acid, diethanolamine, and synthetic organic molybdenum compounds. The molybdenum content of antioxidant synthesized by 3 methods was obtained, which is from 1.0% to 3.5%. The antioxidant properties were evaluated with the Fenton oxidation experiments and differential scanning calorimetry instrument. The results showed that synthetic antioxidants can significantly improve the oxidation stability of oil.
