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

The paper describes the results of the research of some heptylalkanoyldisulfides as antimicrobial additives to the lubricating oils. Heptylalkanoyldisulfides were synthesized and studied. The synthesized compounds were characterized by spectroscopic techniques. Study of antimicrobial properties of the studied heptylalkanoyldisulfides revealed effective bactericidal and fungicidal activities in suppression of fungi and bacteria allowing them to be used as biocides in storage and transportation of oil products. Antimicrobial efficacy of the studied compounds was determined by zonal diffusion method using the following microorganisms: bacteria, fungi and yeast. The test compounds were added to M-8 oil in mass percent. It is established that their antimicrobial activity is at the level of effectiveness of the widely used industrial additive sodium pentachlorophenolate. Sodium pentachlorophenolate, widely applied as an antimicrobial additive in lubricating oils, was used for comparison. It was determined that they may be used as antimicrobial additives for M-8 engine oil (0.25-1%). As a result of the studies carried out on heptylalkanoyldisulfides, distinct patterns of dependence of antimicrobial efficacy on the structure of alkyl radical were determined. Antimicrobial activity increases by an increase in alkyl radical, i.e., each subsequent member of the disulfide series is biologically more active than the previous one. The increase in antimicrobial activity seems to be due to the fact that the adding each new CH2 group gives one more van der Waals bond, increasing adsorption forces that bind the compound to the receptor in the microorganism. As a result of the studies carried out on heptylalkanoyldisulfides, distinct patterns of dependence of antimicrobial efficacy on the structure of alkyl radical were determined
