Abstract

The invention relates to a sulfur-phosphor-free oil-soluble organic molybdenum additive. A technical scheme adopted in the invention is that a preparation method of the additive comprises the following steps: 1, placing castor oil and diethanolamine in a container, reacting for 4-5h under conditions that the temperature is 90-100DEG C and the pressure is a negative pressure, adding oleic acid, and reacting for 2-4h to obtain mixed castor oil amide and oleic acid amide; and 2, mixing the prepared mixed castor oil amide and oleic acid amide with ammonium molybdate, uniformly stirring, adding hydroxyethyl ethylenediamine, reducing the pressure to 13.33-20KPa at 70-80DEG C, reacting for 4-5h, adding polyethylene glycol to wash, separating out a transition layer, cooling the transition layer, and filtering to obtain the brown-red sulfur-phosphor-free oil-soluble organic molybdenum additive. In the additive, the molybdenum content is 7.5%, and the nitrogen content is 3.5%. The production method of the invention has the advantages of simplicity and low cost; and the product (the additive) has the advantages of stable molybdenum structure, good oil solubility, high yield and environmentalprotection.

Description

Technical field [0001] The invention belongs to the field of chemical synthesis, and specifically relates to the synthesis of a non-sulfur-phosphorus type oil-soluble organic molybdenum lubricating oil and lipid additives. Background technique [0002] The non-sulfur-phosphorus organic molybdenum additive is an oil-soluble molybdenum-ammonia complex, which is compatible with molybdenum dialkyl dithiophosphate (MoDTP), molybdenum thiophosphorus nitrogen, molybdenum dialkyl dithiocarbamate (MoDTC), etc. It is a widely used organic molybdenum product on the market. [0003] The difference from molybdenum dialkyl dithiophosphate, molybdenum thiophosphorus nitrogen and molybdenum dialkyl dithiocarbamate is that the molecular structure of non-sulfur-phosphorus organic molybdenum additives does not contain phosphorus and sulfur. It is also a friction modifier, anti-wear agent and anti-sensitizer for lubricating oils, especially lubricating oils for internal combustion engines. [0004] In...
