    • PURPOSE: Specific substituted aromatic ester compounds are useful as lubricity additives for middle distillate fuel oils. CONSTITUTION: Provided is a fuel oil composition obtainable by the addition of a minor proportion of a compound comprising one or more aromatic ring systems, wherein at least one of the ring systems bears, as substituents; (i) one or more hydrocarbon groups imparting oil solubility to the compound, and (ii) one or more hydroxyl groups or derivatives thereof or both, and (iii) one or more ester groups of the formula wherein R" represents an alkyl group optionally substituted by one or more heteroatom-containing groups to a major proportion of a liquid hydrocarbon middle distillate fuel oil having a sulphur concentration of 0.2 wt.% or less, based on the weight of fuel. The composition is represented by general formula I wherein Ar represents an aromatic ring system; B represents a hydrocarbon group (i); OR' represents a hydroxyl group or derivative thereof (ii) wherein R' represents hydrogen, or a hydrocarbyl group, or a group of the formula Hyd roca rbyl-t M alkylene wherein M represents an oxygen atom or an NH group and n represents a number from 1 to 50, and wherein R' may be bonded either directly to the oxygen depending from the ring system or indirectly via a linking group; -COOR" represents an ester group (iii) wherein R" represents an alkyl group optionally substituted by one or more hydroxyl groups.
    • 目的:特定取代的芳族酯化合物可用作中间馏分燃料油的润滑添加剂。 构成:提供一种燃料油组合物,其通过加入少量的包含一个或多个芳香环体系的化合物而获得,其中至少一个环体系作为取代基; (i)一种或多种赋予该化合物油溶性的烃基,和(ii)一种或多种羟基或其衍生物或两者,和(iii)一种或多种下式的酯基,其中R“表示任选的烷基 被一个或多个含杂原子基团取代为大部分基于燃料重量的硫浓度为0.2重量%以下的液体烃中间馏分燃料油,其组成由通式I表示,其中Ar 表示芳环体系; B表示烃基(ⅰ); OR'表示羟基或其衍生物(ⅱ),其中R'表示氢或烃基,或式formula ca yl t t t 亚烷基,其中M表示氧原子或NH基,n表示1至50的数,并且其中R'可以直接键合到氧上,取决于环系或间接经由连接基团; -COOR“表示 埃斯特 r基团(iii)其中R“表示任选被一个或多个羟基取代的烷基。
