SYNTHESIS OF AMINOMETHYL DERIVATIVES OF 3-MERCAPTO-2- HYDROXYPROPYL-1-ISOBUTYL ETHER AND THEIR STUDY AS PROTECTIVE ADDITIVES TO LUBRICANT OILS

The electrochemical corrosion prevention of engines and mechanisms is a task great national, economic defense importance. Lubricating oils commonly used in engineering do not have sufficient protective properties are unable to effectively protect it from corrosion, both during operation short-term long-term inactivity. One the simplest most rational ways solve this problem use lubricants containing effective (conservation) additives, which, without worsening normal working provide them conservation properties. By action 3-mercapto-2- hydroxypropyl-1-isobutyl ether, taken as synthon, with secondary aliphatic heterocyclic amines under conditions Mannich reaction, number aminomethyl derivatives were synthesized. Aminomethyl 3-mercapto-2-hydroxypropyl-1-isobutyl ether dissolved well stable storage. synthesized compounds studied M-12 oil. best test results obtained 3-piperidinomethilthio-2-hydroxypropyl-1-isobutyl - at concentration 1% lubricating oil M-12, steel plate humid chamber 3%, sea water after 24 hours – 5%, 0.1% acid solution HBr 3,5%. These higher than those standard industrial additive urea succinimide. (SIM).
