Compounds containing nitrogen and esters have the potential to become effective lubricating oil additives with antioxidant and anti-wear properties and may also be useful in controlling atmospheric corrosion. The addition of heteroatoms into the molecules of such compounds can significantly improve the characteristics of lubricants. The operational properties of lubricant materials must be studied in detail, including an analysis of their dynamic viscosity, which helps to determine the condition of the oil at various temperatures. The purpose of this work is to study the relationship between the dynamic viscosity of the nitrogen-containing derivatives of alkenyl succinic acids, with a change in the rotation speed at various temperatures. This measurement allows us to determine how the viscosity of this material changes depending on the temperature and the speed of the shift. These data can be useful for understanding the behavior of amides in various conditions, which is important for its use in various industries. Such studies make it possible to optimize the processes of production and use of this material. Analysis of the data shows that an increase in the number of methylene groups in the amide fragment of monooctyl ester amides of octenyl succinic acid has almost no effect on their dynamic viscosity. And with a change in the alkoxy group in the amidoester molecule, that is, from- OC8H17 8 H 17 to-OCH2CH2OH, 2 CH 2 OH, it leads to an increase in dynamic viscosity. In this study, the dependence of the dynamic viscosity of nitrogen-containing derivatives of alkenyl succinic acids on the rotation speed was analyzed at temperatures of +20, +10, 0 and- 10 degrees C. The results o btained confirmed that all amidoesters of alkenyl succinic acids are non-Newtonian liquids. The structural features and composition of organic compounds can significantly affect their operational properties, including dynamic viscosity, which can be important when creating new lubricants
