Problems solved by technology
[0004] At present, sulfur-free and phosphorus-free organic molybdenum additives have good anti-wear and anti-friction properties, but most of them have high acid value, while internal combustion engine oil is an alkaline system, and high acid value will cause premature acidification and deterioration of internal combustion engine oil , shorten the service life of internal combustion engine oil, and it is not conducive to its anti-wear and anti-friction effect

Abstract
The invention provides an organic molybdenum additive, a preparation method thereof and a lubricating oil composition containing the organic molybdenum additive. The organic molybdenum additive is prepared by reacting fatty acid amide, polyisobutene succinimide and an inorganic molybdenum compound; and unessential diluent oil can also be added into the reaction system. When the organic molybdenum additive is prepared, the reaction temperature is 100 to 180 DEG C, and the reaction time is 1 to 10 hours; and molybdenum is 0.1 to 12 percent of the mass of the organic molybdenum additive. The preparation method for the organic molybdenum additive is simple, the conversion rate is high in the reaction process, residue is avoided, and the filtration step is not required; and the organic molybdenum additive has a relatively low acid value, has high solubility in base oil for lubricating oil, and has good abrasion resistance and antifriction performance.
Description
technical field [0001] The invention relates to an organic molybdenum additive, a preparation method thereof and a lubricating composition containing the additive, in particular to a low acid value, sulfur-free and phosphorus-free organic molybdenum additive, a preparation method thereof and a lubricating oil composition containing the additive. Background technique [0002] Sulfur-free and phosphorus-free organic molybdenum additives are widely used in high-grade internal combustion engine oils, which can meet the increasingly stringent energy-saving and environmental protection requirements. [0003] US Patent No. 4,889,647 discloses a sulfur-free and phosphorus-free organic molybdenum lubricating oil additive prepared by reacting animal and vegetable oils, diethanolamine and an inorganic molybdenum compound. The additive has anti-wear and friction-reducing properties. U.S. Patent No. 5,137,647 discloses an organic molybdenum lubricating oil additive prepared by the reacti...
