Abstract
本发明提供一种包含基油和一种或多种聚(羟基羧酸)酰胺盐衍生物的润滑组合物优选在内燃发动机中改进活塞清洁性方面的用途,所述活塞清洁性具体按TU5(CEC L-88-TO 2)和ASTM D6984中的一种或多种进行测试。优选地,一种或多种聚(羟基羧酸)酰胺盐衍生物的TBN值(总碱值)低于10mg.KOH/g。
Description
技术领域
本发明涉及特别用于内燃发动机中的润滑油的用途。
背景技术
WO 2007/128740公开了应用聚(羟基羧酸)酰胺盐衍生物以减少内燃发动机内的沉积物。
按照本发明已经令人惊奇地发现,聚(羟基羧酸)酰胺盐衍生物不仅能抑制内燃发动机的结垢,在减少沉积物如油渣和清漆方面表现出有利的清洁性能,表现出令人惊奇的有利的降低磨擦性能和耐磨特性,而且还表现出改进的活塞清洁性。
发明内容
因此,本发明提供一种润滑组合物,所述润滑组合物包含:
基油;和
一种或多种具有如下通式(III)的聚(羟基羧酸)酰胺盐衍生物
[Y-CO[O-A-CO]n-Z-R+]mpXq- (III)
其中Y为氢或任选取代的烃基,A为任选取代的二价烃基,n为1-100,优选为1-10,m为1-4,q为1-4,和p为整数使得pq=m,Z为任选取代的二价桥基团,该二价桥基团通过氮原子连接到羰基上,R+为铵基,和Xq-为阴离子;
所述组合物优选在内燃发动机中用于改进活塞清洁性,所述活塞清洁性具体按TU5(CEC L-88-TO 2)和ASTM D6984中的一种或多种进行测试。
在这一方面应注意的是:一方面油渣和清漆沉积物和另一个方面活塞沉积物在化学上是不同的,且它们通过不同的过程形成。
如上面提到的WO 2007/128740中所述(具体参见第2页第12-23行),在不同的发动机条件下通过润滑油组合物组分与污染物之间复杂的相互作用形成油渣和清漆沉积物。在低温操作条件例如短的汽车行程下,润滑油组合物可能还不够热,不足以使污染物如水和燃料组分蒸发。在高温下,润滑油组合物可能会氧化,产生反应性基团并变稠。这些条件促使未燃烧或部分燃烧的燃料、水、烟灰、酸、吹出气和其它污染物发生反应,从而形成油渣和清漆。
与之相比较,活塞沉积物(该沉积物按本发明特别要避免)为硬碳沉积物,形成于润滑油和燃料在热表面上的碳化。这些沉积物的碳含量比烟灰低,且通常含有油状物质和灰分。它们通常在活塞顶部区域和冠处以及活塞环槽中发现。
在本发明的通式(III)中,R+可以为伯、仲、叔或季铵基团。R+优选为季铵基团。
在通式(III)中,A优选为直链或支链的二价烃基,正如下文针对通式(I)和(II)所述。
也就是说,在通式(III)中,A优选为任选取代的芳族、脂族或脂环族直链或支链的二价烃基。更优选地,A为亚芳基、亚烷基或亚烯基,特别是含有4-25个碳原子、更优选为12-20个碳原子的亚芳基、亚烷基或亚烯基。
在通式(III)所述的化合物中优选有至少4个碳原子、更优选8-14个碳原子直接连在羰基和衍生自羟基的氧原子之间。
在通式(III)的化合物中,在基团A中的任选取代基优选选自羟基、卤素或烷氧基,特别是C1-4烷氧基。
在通式(III)中,Y优选为如前文针对通式(I)所述的任选取代的烃基。
也就是说,在通式(III)中任选取代的烃基Y优选为含至多50个碳原子、更优选为7-25个碳原子的芳基、烷基或链烯基。例如,任选取代的烃基Y可以适宜地选自庚基、辛基、十一烷基、月桂基、十七烷基、十七烯基、十七碳二烯、硬脂酸基、油基和亚油基。
在这里在通式(III)中所述的任选取代的烃基Y的其它例子包括:C4-8环烷基如环己基;多环烷基如衍生自天然存在的酸如松香酸的多环萜烯基;芳基如苯基;芳烷基如苯甲基;和多芳基如萘基、联苯基、对乙酰氨苯酸钠和苯基甲基苯基。
在本发明中,在通式(III)中,任选取代的烃基Y可以含有一个或多个官能团如羰基、羧基、硝基、羟基、卤素、烷氧基、氨基(优选为叔氨基(没有N-H键))、氧、氰基、硫酰基和亚硫酰基。在取代的烃基中,非氢的大多数原子通常为碳,而杂原子(如氧、氮和硫)通常只占所存在的总非氢原子的少数,如占约33%或更少。
本领域的熟练技术人员将理解在取代烃基Y中官能团如羟基、卤素、烷氧基、硝基和氰基将替代烃基的一个氢原子,而在取代烃基中官能团如羰基、羧基、叔氨基(-N-)、氧、硫酰基和亚硫酰基将替代烃基的-CH-或-CH2-组分。
更优选地,在通式(III)中的烃基Y未取代或被选自羟基、卤素或烷氧基(甚至更优选为C1-4烷氧基)的基团取代。
最优选地,在通式(III)中任选取代的烃基Y为硬脂基、12-羟基硬脂基、油基或12-羟基油基和衍生自天然油如牛油脂肪酸的那些物质。
在通式(III)中,Z优选为由通式(IV)表示的任选取代的二价桥基团:
其中R1为氢或烃基,和B为任选取代的亚烷基。
可以表示R1的烃基的例子包括甲基、乙基、正丙基、正丁基和十八烷基。可以表示B的任选取代的亚烷基的例子包括亚乙基、三亚甲基、四亚甲基和六亚甲基。
在通式(III)中优选的Z部分的例子包括-NHCH2CH2-、-NHCH2C(CH3)2CH2-和-NH(CH2)3-。优选地,R+可以由通式(V)表示:
其中R2、R3和R4可以选自氢和烷基如甲基。
优选地,通式(III)的化合物的阴离子Xq-为含硫的阴离子。更优选地,所述阴离子选自硫酸根和磺酸根阴离子。
可以通过胺和通式(I)的聚(羟基羧酸)与酸或季铵化试剂反应获得一种或多种聚(羟基羧酸)酰胺盐衍生物:
Y-CO[O-A-CO]n-OH (I)
其中Y为氢或任选取代的烃基,A为任选取代的二价烃基,和n为1-100,优选为1-10。
如这里所应用的,术语″烃基″代表通过从烃的碳原子上脱除一个或多个氢原子而形成的基团(当脱除多个氢原子时不需要从相同的碳原子上脱除)。
烃基可以是芳族、脂族、非环状或环状基团。优选地,烃基为芳基、环烷基、烷基或链烯基,在这种情况下它们可以为直链或支链基团。代表性的烃基包括苯基、萘基、甲基、乙基、丁基、戊基、甲基戊基、己烯基、二甲基己基、辛烯基、环辛烯基、甲基环辛烯基、二甲基环辛基、乙基己基、辛基、异辛基、十二烷基、十六碳烯基、二十烷基、二十六烷基、三十烷基和苯基乙基。
在本发明中,短语″任选取代的烃基″用来描述任选含有一个或多个含″惰性″杂原子的官能基的烃基。″惰性″指所述官能团不以任何明显程度干扰化合物的功能。
在这里,通式(I)中任选取代的烃基Y优选为含至多50个碳原子、更优选为7-25个碳原子的芳基、烷基或链烯基。例如,任选取代的烃基Y可以适宜地选自庚基、辛基、十一烷基、月桂基、十七烷基、十七烯基、十七碳二烯基、硬脂基、油基和亚油基。
这里在通式(I)中所述的任选取代的烃基Y的其它例子包括:C4-8环烷基如环己基;多环烷基如衍生自天然存在的酸如松香酸的多环萜烯基;芳基如苯基;芳烷基如苯甲基;和聚芳基如萘基、联苯基、对乙酰氨苯酸钠和苯基甲基苯基。
在本发明中,任选取代的烃基Y可以含有一个或多个官能团,如羰基、羧基、硝基、羟基、卤素、烷氧基、叔氨基(没有N-H键)、氧、氰基、硫酰基和亚硫酰基。在取代的烃基中,非氢的大多数原子通常为碳,杂原子(如氧、氮和硫)通常只占所存在的非氢原子总数的少数,为约33%或更少。
本领域的熟练技术人员将理解,在取代的烃基Y中的官能团如羟基、卤素、烷氧基、硝基和氰基将替代所述烃基的一个氢原子,而在取代烃基中的官能团如羰基、羧基、叔氨基(-N-)、氧、硫酰基和亚硫酰基将替代所述烃基中的-CH-或-CH2-部分。
在通式(I)中,烃基Y更优选为未取代的或被选自羟基、卤素或烷氧基(甚至更优选为C1-4烷氧基)的基团所取代。
最优选地,在通式(I)中,任选取代的烃基Y为硬脂基、12-羟基硬脂基、油基、12-羟基油基或衍生自天然油如牛油脂肪酸的基团。
在本发明的优选实施方案中,一种或多种聚(羟基羧酸)酰胺盐衍生物为含硫的聚(羟基羧酸)酰胺盐衍生物。
