Lubricant and fuel compositions containing hydroxy polycarboxylic acid esters
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.
