Paragraph 0004; 0011, (2016/11/24)
The present invention discloses a water-soluble 2-mercapto benzothiazole phosphate anti-rust agent. According to the present invention, a sulfuric acid solution is adopted as a solvent, 2-mercapto benzothiazole and alpha-alkenyl acid are subjected to a reaction, the compound generated from the reaction is subjected to suction filtration, the filter cake is subjected to alkali dissolving, suction filtration is performed again, filtrate acidification is performed, other purification methods are performed, the obtained material reacts with diethanolamine, and the amidation product generated from the reaction and phosphorus pentoxide are further subjected to an esterification reaction to generate the water-soluble 2-mercapto benzothiazole phosphate anti-rust agent; the synthesized product has good water solubility; the water-soluble 2-mercapto benzothiazole phosphate anti-rust agent is an organic heterocyclic carboxylic acid amide phosphate, has the multiple slow-release group and metal combining characteristic, and further has excellent rust resistance; and the synthesized product has the extreme pressure property.
