Problems solved by technology

However, some commonly used organic molybdenum products contain sulfur and phosphorus elements, and some only contain phosphorus elements. Because sulfur and phosphorus elements are not good for exhaust emissions, the industry expects the introduction of non-sulfur and phosphorus organic molybdenum products.

Embodiment 1

[0024] The preparation of embodiment 1 bis-isooctylamine molybdenum complex

[0025] Under the environment of nitrogen flow protection, uniformly disperse 1 mole of molybdenum trioxide solid powder in 540 ml of aqueous solution, then slowly add 0.5 mole of 60% sulfuric acid, and then slowly add 1.2 moles of bis-isooctyl secondary amine to the dispersion (recommended to complete within one hour). The temperature of the reaction system is controlled between 50° C. and 60° C., and the reaction time is about one hour. Then the upper water layer was removed to obtain a light blue crude product, which was washed, filtered and evaporated to obtain the finished product. After testing, the elemental content of the product sample: molybdenum content 22.8%, nitrogen content 3.6%. It is speculated that the product is a bis-isooctylamine molybdenum complex (R is a branched C 8 Alkyl, and has the above general structural formula).

Embodiment 2

[0026] The preparation of embodiment 2 bis-octylamine molybdenum complexes

[0027] Under the environment of nitrogen flow protection, uniformly disperse 1 mole of molybdenum trioxide solid powder in 540 ml of aqueous solution, then slowly add 0.5 mole of 60% sulfuric acid, and then slowly add 1.2 mole of bis-n-octyl secondary to the dispersion. Amines (recommended within one hour). The temperature of the reaction system is controlled between 50° C. and 60° C., and the reaction time is about 1 hour. Then the upper water layer was removed to obtain a light blue crude product, which was washed, filtered and evaporated to obtain the finished product. After testing, the elemental content of the product sample: molybdenum content 22.4%, nitrogen content 3.5%. After speculation, the product is bis-octylamine molybdenum complex (R is C 8 And has the above general structural formula).

Embodiment 3

[0028] The preparation of embodiment 3 ditridecylamine molybdenum complexes

[0029] Under the environment of nitrogen flow protection, uniformly disperse 1 mole of molybdenum trioxide solid powder in 540 ml of aqueous solution, then slowly add 0.6 mole of 60% sulfuric acid, and then slowly add 1.5 mole of ditricone to the dispersion Alkyl secondary amines (recommended within one hour). The temperature of the reaction system is controlled between 60° C. and 70° C., and the reaction time is about 1.5 hours. Then the upper water layer was removed to obtain a light blue crude product, which was washed, filtered and evaporated to obtain the finished product. After testing, the elemental content of the product sample: molybdenum content 16.4%, nitrogen content 2.3%. After guessing, this product is ditridecylamine molybdenum complex (R is C 13 And has the above general structural formula).

Abstract

The invention provides an oil-soluble non-sulfur-phosphor organic molybdenum compound which has a structure as shown in the following general formula: R2NMoO3H.nH2O (n=0,1), wherein R is C4-C13 straight chain or branched-chain alkyl group; and two alkyl groups R can be the same or different. The non-sulfur-phosphor organic molybdenum compound provided by the invention is used as an additive to be applied in a lubricating oil product, has functions of reducing friction, enhancing anti-wear and extreme pressure performance, raising antioxidation performance of the lubricating oil product, maintaining fuel economy for a long time and prolonging oil change period of the lubricating oil product, and has good addition and cooperative effects with other routine functional additives.

Description

technical field [0001] The invention relates to an oil-soluble non-sulfur phosphorus organic molybdenum compound, its preparation method and its application in lubricating oil. Background technique [0002] Molybdenum-containing compounds have been used for a long time as antioxidant and anti-friction additives for internal combustion engine oils, gear oils, greases and some industrial oils. It has been widely used in North America, Western Europe, Japan and other developed countries and regions with strict energy saving and environmental protection requirements. for a long time. The excellent performances of friction reduction, energy saving and environmental protection of these products have been widely praised and praised by the lubrication industry. In view of the functions of organic molybdenum compounds in reducing friction, anti-wear, anti-oxidation, energy saving, and reducing air pollution, domestic and foreign research and development of organic molybdenum are ve...
