This work evaluated the efficiency of two types of synthesized Amides (demulsifiers) Oleic Ethylene Diamine (OED) and Oleic Methyl Aniline (OMA) in the Laboratory by variating time(5, 10, 15, 20, 25, 30) minute at constant temperature (ºC) and concentration. Both demulsifiers are prepared by the reflux method. Oleic Ethylene Diamine (OED) was prepared by the reaction between Oleic acid and ethylene di amine. Methyl aniline (p-toluidine) was prepared by the reaction between oleic acid and methyl aniline. FTIR and H.NMR spectra were used to diagnose the synthesized demulsifier's structure. A comparison between these types of demulsifiers was made. The photos show the amount of separation between the water and oil phases. Demulsifiers showed high efficiency in the separation process of water from crude oil.
