The present invention is related to a process for obtaining organic ammonium salts (OAS) and their derivatives, supramolecular surfactants (SS), which simultaneously present the properties of traceability and detergents dispersant of organic scales. Organic ammonium salts (OAS) and their derivatives supramolecular surfactants (SS) have applications as differentiators, markers, or tracers in fuels derived from hydrocarbons; and also to disperse organic scales or inhibit the gums precipitation both in injectors and intake valves of automotive vehicle engines. Organic ammonium salts (OAS) are obtained through an acid-base reaction between a molecule from the azo family and an amine. Once the OAS is obtained, it reacts with an organic compound (OC) so that through non-covalent interactions, a self-assembly process occurs that gives rise to the SS. Said process is based on green chemistry, that is, in the absence of solvents. These OAS and SS are quantified through the analytical techniques of ultraviolet-visible (UV-VIS) and high-performance liquid chromatography (HPLC) through a calibration curve. Additionally, its performance as a gum-dispersing agent in a single-cylinder engine is evaluated.
