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 environmental protection.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to the synthesis of nonthion-phosphorous oil-soluble organic molybdenum lubricating oil and lipid additive compounds. Background technique [0002] Non-sulfur phosphorus organic molybdenum additive is an oil-soluble molybdenum ammonia complex, which is compatible with molybdenum dialkyldithiophosphate (MoDTP), sulfur phosphorus nitrogen molybdenum, molybdenum dialkyldithiocarbamate (MoDTC), etc. It is the most widely used organic molybdenum product in the market. [0003] The difference from dialkyl dithiophosphate molybdenum, sulfur phosphorus nitrogen molybdenum and dialkyl dithiocarbamate molybdenum is that the molecular structure of the non-sulfur phosphorus organic molybdenum additive does not contain phosphorus and sulfur. It is also a friction modifier, antiwear agent and antisensitizer for lubricating oil, especially lubricating oil for internal combustion engi...
