Thioamide Compounds as Additives to Petroleum Oils

Abstract

Thioamides are widely used in the chemical industry, engineering and agriculture due to their reactivity and chemical properties. However, these compounds have been little studied as additives used to improve the quality of oils used in machines and mechanisms. For this purpose, scientific research has been conducted in the direction of studying the improvement of the anti-corrosion and anti-wear properties of n-chlorophenylthioacetamides as additives to lubricating oils. Due to their chemical properties and reactivity, thioamides are used in the chemical industry, engineering, agriculture, etc. They are an indispensable raw material in the production of rubber as vulcanization accelerators, flotation reagents and components of preservative liquids. Studies have shown that thioamides, such as n-chlorophenylthioacetamide, have been little studied as additives to improve the quality of lubricating, hydraulic and mineral oils of petroleum origin. The article is devoted to the study of the properties of thioamide compounds as additives to lubricants and hydraulic oils. It was studied that additives with secondary and tertiary amines with the same alkyl radical have the same ability to reduce the corrosion rate. Thioamides of the phenyl radical are more effective additives due to their thermal-oxidizing ability compared to alkyl and heterocyclic radicals and exhibit their effect in these oils. The addition of isopropyl-p-chlorophenylthioacetamide was taken into account and the absence of precipitation in the oxidized oil and an increase in viscosity were confirmed.
