- W2914279547 abstract "Five new surfactants derived from Sudanese Jatropha oil were synthesized. Three of them, namely: Surfactant-1 (SF-1), Surfactant-2 (SF-2) and Surfactant-3 (SF-3) were methyl ester sulphonate of Jatropha oil from different locations of South Kordofan, Ad-Damazin and Al Qadarif, respectively. Surfactant-4 (SF-4) and Surfactant-5 (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 (1-3) showed reduction in the measurement of interfacial tension almost similar to that of the standard surfactant used in the field (sodium methyl ester sulphonate). SF (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 (using a homogenizer) in the presence or absence of surfactant showed that, SF (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 (EOR) application." @default.
