Patent number: 12359141Abstract: The present invention discloses polyethyleneamine salts of sulphonyl oleic acid and a 5 hydrocarbon fuel additive composition comprising the same. The said polyethyleneamine salts of sulphonyl oleic acid is made by mixing a sulphonyl oleic acid with at least one polyethyleneamine. Wherein, the sulphonyl oleic acid is selected from at least one of (9Z)-8-sulfo-octadec-9-enoic acid or (9Z)-11-sulfo-octadec-9-enoic acid. The at least one polyethyleneamine is selected from triethylenetetramine (TETA), or diethylenetriamine 0 (DETA), pentamethyldiethylenetriamine, tetraethylenepentamine, 1,4,7-triazacyclononane, 1,1,1-Tris(aminomethyl)ethane, or cyclen. The hydrocarbon fuel additive composition is made of polyethyleneamine salts of sulphonyl oleic acid and a cosolvent system consisting of sulphonyl oleic acid and dioxane. Wherein, the said hydrocarbon fuel additive composition acts as a dual functional additive and synergistically improves the conductivity as well as 5 lubricity of a hydrotreated diesel fuel.Type: GrantFiled: September 15, 2021Date of Patent: July 15, 2025Assignee: Hindustan Petroleum Corporation LimitedInventors: Sandip Bhowmik, Naresh Kottari, Chintalapati Siva Kesava Raju, Ramesh Kandanelli, Ravi Balasubramaniam
