In this scientific-research work, surfactants were synthesized from three different fatty acids, dodecanoic, tetradecanoic and hexadecanoic acid, with the participation  of  N1-(2-Aminoethyl)ethane-1,2-diamine and many of their properties were comparatively analyzed. The structure and composition of the obtained compounds were identified by IR and UV spectroscopy. In addition, the thermal characteristics of the complexes and the mass changes during the processes caused by the influence of temperature were studied by TG, DTA analysis. The thermal properties were studied in the “STA 449 F3” Jupiter (Germany, “NETZSCH”) synchronous thermoanalyzer, in the thermoprogrammed dynamic mode in an inert (nitrogen) environment in the range of  20–600 oC, starting from room temperature and increasing the temperature at a rate of 10 oC/min.
Finally, in order to investigate the use of surfactants in the removal of oil spills from a water basin, petrocollecting and petrodispersing properties were studied in three different water samples with different salinity and mineralization. From the moment surfactant is issued, observations are made, the surface area of the oil slick is measured at certain time intervals and the value of K is calculated. When the crude oil layer is dispersed, the water surface cleaning coefficient (Kd) is measured as a percentage at certain time intervals.
