Amide/Amino-Based Functional Additives for Lubricants: Structure, Antimicrobial Activity and Wear Resistance
The lubricating properties of the lubricants were tested under boundary friction conditions; it was found that the surface-active additives had reduced the wear mark and thus the value of the Goz/40 parameter (limiting load of wear).

| description | The lubricating properties of the lubricants were tested under boundary friction conditions; it was found that the surface-active additives had reduced the wear mark and thus the value of the Goz/40 parameter (limiting load of wear). The introduction of a surfactant containing amide compounds into the oils and greases was highly effective in slowing down the oxidation process. Lubricants containing mono–15 ([3-(<i>N</i>,<i>N</i>,<i>N</i>-dimethylbuthylamine)propyl]hexadecanamide chloride) and 15–4–15 (tetramethylene-bis [3-(<i>N</i>,<i>N</i>,<i>N</i>-dimethylamine)propyl]hexadecanamide) additives were characterised by higher oxidation stability compared to the unmodified lubricants. Both of the analysed substances showed bactericidal properties against <i>Staphylococcus aureus</i> and <i>Salmonella enteritica</i>. Tests of antibacterial activity in the lubricants with the addition of mono–15 and 15–4–15 confirmed that these lubricants can be considered bactericidal against Gram-positive and Gram-negative bacteria. |
