    • The present invention provides for a middle distillate fuel having a boiling range within about 120.degree. to about 400.degree. C. which has enhanced low temperature flow properties. These enhanced properties are provided by the addition of a mixture comprising:a) the sulfonamide or amine salt reaction product of an alkylaryl sulfonic acid having from about 10 to about 70 carbon atoms and a primary, secondary tertiary or quaternary amine having from 4 to about 40 carbon atoms;b) an alkyl diphenyl ether wherein the alkyl group contains from about 16 to about 44 carbon atoms; andc) an oil soluble nitrogen-containing compound containing a total of about 30 to about 300 carbon atoms and having at least one straight chain alkyl segment of 8 to 40 carbon atoms and selected from the class consisting of the amine salt and/or amide reaction product of a hydrocarbyl carboxylic acid or anhydride having 1 to 4 carbonyl groups and a primary, secondary, tertiary or quaternary amine having from 4 to about 40 carbon atoms.This mixture may be added to very low levels to middle distillate oils, i.e., diesel and home heating oil, to yield fuel products having enhanced cold flow properties.
    • 本发明提供了沸点范围在约120℃至约400℃的中间馏分燃料,其具有增强的低温流动性能。 这些增强的性质通过加入混合物来提供,所述混合物包括:a)具有约10至约70个碳原子的烷基芳基磺酸的磺酰胺或胺盐反应产物和具有4至约70个碳原子的伯,仲叔或季胺 40个碳原子; b)烷基二苯基醚,其中烷基含有约16至约44个碳原子; 和c)含有总共约30至约300个碳原子并且具有至少一个具有8至40个碳原子的直链烷基部分并且选自胺盐和/或酰胺类的油溶性含氮化合物 具有1至4个羰基的烃基羧酸或酸酐和具有4至约40个碳原子的伯,仲,叔或季胺的反应产物。 该混合物可以以非常低的水平添加到中间馏分油,即柴油和家用加热油中,以产生具有增强的冷流特性的燃料产品。
