A composition of matter is disclosed wherein the composition comprises an N-aromatic substituted acid amide compound selected from the group consisting of compounds of formula (I) wherein A and B are independently selected alkylene groups; R
1
is selected form the group consisting of hydrogen, alkyl alkylether, or ester; R
2
is hydrogen if R
1
is hydrogen; R
2
is an alkyl primary amine if R
1
is alkyl, alkylether, or ester, R
3
and R
4
are independently selected from the group consisting of hydrogen and alkyl; R
5
is a sterically hindered phenolic group of formula (II) or formula (III) wherein X is CH
2
, S, NH, or O; and m, n, and p are independently selected integers equal to 0 or 1. These compositions may be used as such or they may be bound to a polymer backbone via a linking moiety. In either case, they are useful as antioxidants, particularly in lubricating oil compositions.
揭示了一种物质组成,其中该组成物包括选择自公式(I)化合物的N-芳基取代酸酰胺化合物,其中A和B是独立选择的烷基基团;R1从由氢,烷基烷醚或酯组成的群中选择;如果R1是氢,则R2是氢;如果R1是烷基,烷基醚或酯,则R2是烷基一级胺,R3和R4是独立选择的氢和烷基的群;R5是公式(II)或公式(III)的立体位阻酚基团,其中X为CH2,S,NH或O;m,n和p是独立选择的等于0或1的整数。这些组成物可以直接使用,或者它们可以通过连接基团与聚合物骨架结合。在任何情况下,它们都可作为抗氧化剂使用,特别是在润滑油组成物中。
