Abstract

The invention relates to a sulfur- and phosphorus-free water-soluble organic molybdenum additive. A technical scheme used in the invention is as follows: oleic acid and diethanolamine are placed in a container and subjected to a reaction for 3 to 5 h at a temperature of 90 to 100 DEG C, then hydroxyethyl ethylenediamine is added, and an obtained mixture is allowed to further react for 2 to 4 h ata temperature of 100 DEG C in vacuum so as to prepare mixed oleylamine, wherein, the weight ratio of oleic acid to diethanolamine is 100: 30-40, and the weight ratio of oleic acid to hydroxyethyl ethylenediamine is 100: 20-30; prepared mixed oleylamine and ammonium molybdate are mixed uniformly with stirring, then imidazole is added, an obtained mixture is subjected to pressure reduction at a temperature of about 70 to 80 DEG C until a mercury column is 100 to 150 mm high, allowed to react for 4 to 5 h, then heated to a temperature of 80 to 100 DEG C, subjected to pressure reduction until a mercury column is 50 to 80 mm high and allowed to further react for 2 to 3 h, then water generated in the reactions is pumped out, and a resultant undergoes cooling and filtering so as to obtain brown-red sulfur- and phosphorus-free water-soluble organic molybdenum with a content of 7.5%, wherein, the content of N is 4.5%, the weight ratio of mixed oleylamine to ammonium molybdate is 100: 30-35, and the weight ratio of mixed oleylamine to imidazole is 100: 15-20. According to the invention, a product is prepared through two-step reduced pressure distillation, and the product has excellent extreme pressure properties, good metal slow release and extraordinary water soluble lubricity.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to the synthesis of a non-sulfur phosphorus water-soluble organic molybdenum additive compound. Background technique [0002] Long-chain fatty acid water-based molybdenum derivatives as a neutral aqueous solution medium, the application of steel corrosion inhibitors and cutting fluid application research has been concerned by scholars from all over the world. As water-soluble additives are moving towards high efficiency, pollution-free and multifunctional With the development and the further strengthening of people's awareness of ecological environment, more and more researchers are trying to use non-nitrous acid, non-sulfur phosphorus long-chain fatty acid amides to provide a chemical barrier to enhance the corrosion inhibition performance of the preparation. In particular, some water-soluble products can improve the anti-rust ability of the product by adding the compo...
