Abstract :Five new surfactants derived from Sudanese Jatropha oil were synthesized. Three of them, namely: Surfactant-1 insert ignore into journalissuearticles values(SF-1);, Surfactant-2 insert ignore into journalissuearticles values(SF-2); and Surfactant-3 insert ignore into journalissuearticles values(SF-3); were methyl ester sulphonate of Jatropha oil from different locations of South Kordofan, Ad-Damazin and Al Qadarif, respectively. Surfactant-4 insert ignore into journalissuearticles values(SF-4); and Surfactant-5 insert ignore into journalissuearticles values(SF-5); were ethyl ester and soap produced from South Kordofan Jatropha oil, respectively. The characterizations were studied by FT-IR and GC with mass, and they approved an excellent formation of functional group of surfactants produced. The execution of every surfactant was considered its emulsification quality and its thermal stability. The emulsification quality of every surfactant was tried by measuring the interfacial pressure between every surfactant and unrefined oil and by measuring the stage separation time between water and unrefined oil in the absence and in the presence of surfactant. Surfactants insert ignore into journalissuearticles values(1-3); showed reduction in the measurement of interfacial tension almost similar to that of the standard surfactant used in the field insert ignore into journalissuearticles values(sodium methyl ester sulphonate);. SF insert ignore into journalissuearticles values(4 and 5); also reduced the interfacial tension, but with less quality. The measurement of phase separation time for a homogenized mixture of 100 ml water and 1.0 ml of crude oil insert ignore into journalissuearticles values(using a homogenizer); in the presence or absence of surfactant showed that, SF insert ignore into journalissuearticles values(1-5); gave more time for phase separation. The results of analysis showed that, these products were real surfactants and it can be used in enhanced oil recovery insert ignore into journalissuearticles values(EOR); application.
