A method for reducing the propensity of a fuel to form an emulsion comprises combining an additive having a chemical structure comprising a 6-membered aromatic ring sharing two adjacent aromatic carbon atoms with a 6- or 7-membered saturated heterocyclic ring, the 6- or 7-membered saturated heterocyclic ring comprising a nitrogen atom directly bonded to one of the shared carbon atoms to form a secondary amine and an atom selected from oxygen or nitrogen directly bonded to the other shared carbon atom, the remaining atoms in the 6- or 7-membered heterocyclic ring being carbon with the fuel. Thus, the additive may be used as a demulsifier in a fuel.
一种降低燃料形成乳状液的倾向性的方法,包括将一种添加剂与一个 6 或 7 元饱和杂环结合,该添加剂的
化学结构包括一个共用两个相邻芳香碳原子的 6 元芳香环和一个 6 或 7 元饱和杂环、该 6 元或 7 元饱和杂环包括一个与其中一个共用碳原子直接键合以形成仲胺的氮原子,以及一个与另一个共用碳原子直接键合的选自氧或氮的原子,6 元或 7 元杂环中的其余原子与燃料同为碳原子。因此,添加剂可用作燃料中的破
乳化剂。
