Abstract

The invention provides a sulfur / phosphorus-free organic molybdenum complex as well as a preparation method and application thereof. The preparation method of the complex is as follows: an organic ligand and a molybdenum source compound react to prepare the complex, and the molybdenum source compound is an acetylacetone complex of hexavalent molybdenum. The complex has a simple structural formula shown as a formula I or a formula II as the specification. The complex is used as an anti-wear and anti-friction additive of lubricating grease, has better oil solubility and tribological properties, can be compounded with a lubricating oil additive to achieve a synergistic effect, does not contain sulfur and phosphorus, is green and environment-friendly, is simple in process, and has a better application prospect.

Description

technical field [0001] The invention belongs to the technical field of organic matter preparation, and relates to a sulfur-free phosphorus organic molybdenum complex and its preparation method and application, in particular to a sulfur-free phosphorus organic molybdenum complex, its preparation method and its application in lubricating oils. Background technique [0002] The rapid development of the automobile industry has exacerbated global energy consumption and environmental pollution. Friction and wear are one of the main factors that cause energy loss, material loss or damage. Various countries have introduced a series of new environmental protection regulations, which require reducing vehicle fuel consumption, reducing emissions and extending engine life. Organic molybdenum is a kind of multi-effect lubricating additive with many advantages such as extreme pressure, anti-wear, anti-friction and anti-oxidation. It is often used as a friction modifier or anti-wear and an...
