Abstract

The invention relates to a magnetic boronized phosphonate amine ester lubricating oil additive. According to the technical scheme, the preparation method comprises the following steps: putting methyl oleate and monoethanolamine into a container to react for 4-5 hours at the temperature of 90 DEG C and the high negative pressure of 80MMHg, and further adding oleic acid to react, thereby obtaining oleamide; mixing oleamide with phosphorus pentasulfide and propyl alcohol, constantly introducing an ammonia gas at high pressure to react for 4-5 hours at 170-180 DEG C, thereby obtaining a phosphonate amine ester compound; mixing phosphonate amine ester with boric acid to react for 4-5 hours at the temperature of 100 DEG C and the high negative pressure of 230MMHg, reducing the pressure to be 30MMHg for further reaction, cooling, and filtering, so as to obtain the boronized phosphonate amine ester lubricating oil additive. By continuously introducing the ammonia gas in a circulation manner by using a two-step pressure reduction method through three steps of reaction, a novel boronized phosphonate amine ester lubricating oil additive which is low in sulfur, low in phosphorus, high in efficiency and contains a boron nitride structure can be prepared, and the prepared product is excellent in wearing resistance, friction reduction and anti-oxidation property, simple in production method, low in cost and stable in product structure.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to the synthesis of a magnetic boronated phosphoric acid amine ester lubricating oil additive and ester additive compounds. Background technique [0002] In order to increase the anti-friction and anti-wear effect of lubricating oil, a small amount of lubricating oil additives are usually added to lubricating oil. Traditional lubricating oil additives are high-sulfur, high-phosphorus or chlorine-containing anti-wear agents. Corrosive and selective, and not environmentally friendly. As for the new mechanism of anti-wear and anti-friction, as early as the mid-1960s, people began to use different experimental instruments and analysis methods to study. The boronated phosphate amine ester containing B, S, P, and N in the molecular structure can greatly improve the anti-wear and anti-friction function of the oil, increase the lubricating and dispersing performance, and the t...
