APPLICATION OF FATTY ACID IMIDAZOLINES AS DIESEL FUEL LUBRICATING PROPERTIES ADDITIVES
The problem of corrosion is still relevant due to the economic damage it causes in various industrial fields of the world, especially in the field of oil processing and transportation. Although many scientific research works and results have been obtained in the direction of solving this problem, scientific researchers are still looking for an effective solution. The most optimal method of corrosion protection, both economically and ecologically, is the method of creating and applying inhibitors.
It is known that nitrogen-containing organic compounds - amines, amides, imidazolines, imidazoles - are successfully used as corrosion inhibitors. The literature provides extensive information on the synthesis, properties and applications of imidazoline compounds and their derivatives. Corrosion inhibitory properties of these compounds depend on their molecular structure. The adsorption of these molecules on the metal surface is determined by the presence of a double bond and a lone pair of electrons in the heteroatom.
As it is known, one of the requirements for modern diesel fuels is to limit the amount of sulfur to one thousandth of a percent (0.005-0.001%). Purification of diesel fuels from compounds containing sulfur, nitrogen and oxygen has a negative effect on the lubricating properties of the fuel. Thus, during hydrocleaning, the process of removing surface-active substances from the fuel, which form a protective layer on the fuel surface, also takes place.
