METHOD OF PRODUCING MULTIFUNCTIONAL FUEL ADDITIVE AND MULTIFUNCTIONAL FUEL ADDITIVE Russian patent published in 2024 - IPC C10L1/22 C10M157/04 

FIELD: fuel industry.

SUBSTANCE: group of inventions relates to a method of producing a multifunctional fuel additive, a multifunctional fuel additive and a fuel composition containing a multifunctional additive, and can be used in chemical and power industries. Disclosed is a method of producing a multifunctional fuel additive. To obtain a first functional component, an oxazolidine derivative is obtained by mixing diethanolamine and formaldehyde in molar ratio of 1.0: 1.0, and then the alkylated phenol and the obtained oxazolidine derivative are mixed in a molar ratio of 0.8–1.2: 1.0. To obtain a second functional component, an amine and a fatty acid are mixed in molar ratio of 0.9–1.1: 1.0. Further, the obtained first and second functional components are mixed in weight ratio of 1.0: 1.0 to 20.0: 1.0. Besides, multifunctional fuel additive and fuel composition are disclosed.

EFFECT: high functional efficiency and stability of properties of the obtained additive.
