Publication number: 20230399576Abstract: The present invention relates to supramolecular surfactants (SS) with detergent-dispersant of heavy organic compounds (deposits and/or organic scales) and corrosion inhibition properties, and methods for preparing these surfactants. The invention also relates to the corresponding uses and applications of these surfactants to prevent and control the formation of deposits in internal combustion machines, as well as to prevent and protect pipelines, tanks, motors and complements of ferrous materials against corrosion where there is contact with liquid hydrocarbons such as gasoline, turbosine, and diesel, where gasoline may contain oxygenated compounds such as ethers and/or alcohols. The supramolecular surfactants are obtained from the self-assembly process between oxazolidines derived from polyalkyl/polyalkenyl N-hydroxyalkyl succinimides with alkyl/alkenyl-amine-propanoic acids and alkyl/alkenyl-amine-di-propanoic acids.Type: ApplicationFiled: June 2, 2023Publication date: December 14, 2023Inventors: Ricardo Cerón Camacho, Raúl Oviedo Roa, Jorge Francisco Ramírez Pérez, Enrique Soto Castruita, Rodolfo Cisneros Dévora, David Aaron Nieto Álvarez, José Manuel Martínez Magadan, Ana Graciela Servín Nájera, Luis Silvestre Zamudio Rivera
