Abstract
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).

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
