    Abstract: A fuel composition of improved lubricity comprises a lubricity-increasing amount of a lubricity aid dissolved in low sulfur diesel fuel and spark ignition fuels. The lubricity aid is an alkanolamide of a fatty acid, an alkanolamide of a modified fatty acid or a mixture thereof. If the lubricity aid is other than an alkanolamide of an aryl-substituted fatty acid, the composition further necessarily comprises a haze-inhibiting amount of a dehazer. The lubricity of such fuels may be enhanced without acceptably increasing the tendency of the fuel to become hazy upon contact with water.

    Abstract translation: 具有改善的润滑性的燃料组合物包括溶解在低硫柴油燃料和火花点燃燃料中的润滑增加量的润滑助剂。 润滑助剂是脂肪酸的链烷醇酰胺，改性脂肪酸的链烷醇酰胺或其混合物。 如果润滑助剂不是芳基取代的脂肪酸的链烷醇酰胺，则组合物还必须包含雾度抑制量的除雾剂。 这种燃料的润滑性可以增强，而不会可接受地增加燃料在与水接触时变得模糊的倾向。

    Abstract: A method for scavenging mercaptans in a hydrocarbon fluid is disclosed. According to the method, an effective mercaptan-scavenging amount of an aqueous scavenging composition is added to the fluid. The composition comprises a quaternary ammonium hydroxide of the formula R.sup.1 R.sup.2 R.sup.3 R.sup.4 NOH. R.sup.1 and R.sup.2 are, independently, alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms or alkylaryl groups of from seven to about eighteen carbon atoms. R.sup.3 is an alkyl group of from two to about eighteen carbon atoms, an aryl group of from two to about eighteen carbon atoms or an alkylaryl group of from four to about eighteen carbon atoms. R.sup.2 and R.sup.3 may be joined to form a heterocyclic ring including the N and optionally an oxygen atom. R.sup.4 is --(CH.sub.2 CH.sub.2 O).sub.n H, wherein n is an integer from one to about eighteen, or --CHR.sup.5 CHR.sup.6 Y, wherein R.sup.5 and R.sup.6 are, independently, hydrogen, alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms or alkylaryl groups of from seven to about eighteen carbon atoms. Y is a non-acidic group. Related compositions and methods are also disclosed.

    Abstract: A method for scavenging sulfur species from a petroleum-derived medium is disclosed. The method comprises contacting the medium with sulfur species scavenging amount of an imine of the formula ##STR1## wherein x is an integer from 1 to 10, R' is an organic moiety having a number of valences equal to x, R.sub.1 is hydrogen or a mono-valent organic moieties and R is a mono-valent olefin moiety, provided that R and R.sub.1 contain a total of from about four to about forty carbon atoms. In an alternative embodiment, the imine is produced by a condensation reactionic between an amine having at least one primary amino group and a carbonyl of the formula ##STR2## wherein R.sub.1 is hydrogen or a mono-valent organic moieties and R is a mono-valent olefin moiety, provided that R and R.sub.1 contain a total of from about four to about forty carbon atoms. In yet other embodiments, the imine is produced by a condensation reaction between an amine having at least one primary amino group and an aldehyde having at least one alpha-hydrogen in an aldehyde to primary amino group molar ratio of at least about 2:1, are also disclosed.
