    摘要: Disclosed herein is a composition comprising:
    (A) a hydrocarbon fuel;
    (B) at least one hydroxy carboxylic or hydroxy polycarboxylic acid ester having
    the following generic formula:


    wherein:
    R 3 is selected from the group consisting of C 1 - C 18 linear or branched alkyl, C 1 - C 18 linear or branched alkenyl, alkoxyalkyl, hydroxyalkyl, aryl, and benzyl; and
    X- is selected from the group consisting of


    and


    wherein:
    R 1 is selected from the group consisting of hydrogen, CH 2 CO 2 R 3 , CH(OH)CO 2 R 3 , alkyl, aryl, alkoxyalkyl, and alkaryl;
    R 2 is selected from the group consisting of hydrogen, alkyl, and CH 2 CO 2 R 3 ;
    provided that:
    if R 1 is CH 2 CO 2 R 3 , then R 2 is hydrogen or CH 2 CO 2 R 3 ;
    if R 1 is CH(OH)CO 2 R 3 , then R 2 is hydrogen;
    if R 1 is alkyl, aryl, alkoxyalkyl, or alkaryl, then R 2 is hydrogen or alkyl;

    R 4 is selected from the group consisting of hydrogen and CH 2 CO 2 R 3 ;
    R 5 and R 6 are independently selected from the group consisting of hydrogen, alkyl,

    and aryl; and
    R 7 , R 8 , R 9 , and R 10 are independently selected from the group consisting of hydrogen, CO 2 R 3 , alkyl, and fused aryl; and, optionally,

    (C) at least one zinc dihydrocarbyldithiophosphate of formula:

    wherein n is 2 and R 2 and R 3 are independently selected hydrocarbyl groups.
