    • The lubricity (anti-wear properties) of fuels, for example hydrocarbon fuels, oxygenated fuels or mixtures thereof, particularly diesel or aviation fuels having reduced sulphur and/or aromatic content for compliance with regulator requirements, is improved by addition of at least a product which can be obtained by reacting components a), b) and c), where component a) is a compound of the formula I or a mixture of compounds of the formula I, component b) is a compound of the formula II or a mixture of compounds of the formula II and component c) is a compound of the formula III or a mixture of compounds of the formula III,
      in which the general symbols are as defined in claim 1, the compound of the formula I being, for example, pentaerythritol, thiodiethylene glycol, 1,4-butanediol, 1,4-propanediol, diethylene glycol, triethylene glycol, diethanolamine or glycerol, the compound of the formula II being, for example, sunflower oil or coconut fat, and the compound of the formula III being, for example, methyl 3-(3',5'-di-tert-butyl-4'-hydroxyphenyl)propionate. The abovementioned products also improve corrosion inhibition.
    • 燃料,例如碳氢化合物燃料,含氧燃料或其混合物,特别是具有降低的硫和/或芳族含量以满足调节器要求的柴油或航空燃料的润滑性(抗磨损性能)通过添加至少一种产物 其可以通过使组分a),b)和c)反应获得,其中组分a)是式I化合物或式I化合物的混合物,组分b)是式II化合物或其混合物 的式II化合物和组分c)的化合物是式III的化合物或式III化合物的混合物,其中一般符号如权利要求1所定义,式I化合物是, 例如季戊四醇,硫二甘醇,1,4-丁二醇,1,4-丙二醇,二甘醇,三甘醇,二乙醇胺或甘油,式II化合物为例如向日葵油或椰子油,化合物 的式III 例如是3-(3',5'-二叔丁基-4'-羟基苯基)丙酸甲酯。 上述产品也提高了腐蚀抑制。
