  • Patent number: 12359141
    Abstract: 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.

  • Publication number: 20240309178
    Abstract: The present invention provides additive compound for warm mix asphalt (WMA) for the paving of road surfaces, whereby the additive compounds facilitate the mixing, lay down and compaction of asphalt mixes at low temperatures while retaining the mechanical properties of the asphalt composition. Further, the present invention provides a process of synthesis of the additive compounds. Additionally, the present invention provides a warm mix asphalt formulation involving the additive compounds and a method of preparation thereof. The chemical additives of the present invention are liquid surfactants that ensure reduction of internal friction during manufacturing, and subsequently formulations comprising these chemical additives results in reduction of compaction temperature of the bituminous mixtures.
