Description

用于烃类混合物的润滑组合物及其获得的产品
技术领域
本发明涉及一种用于烃类混合物的组合物，尤其是低硫含量的烃类混合物。本发明的目的是提高烃类混合物的润滑性能，减轻烃类混合物与金属零部件接触时的腐蚀程度，并能通过提高导电性增强其抗静电性能。这种组合物适用于为陆地交通工具或飞机提供能源的全合成或半合成烃类混合物，尤其适用于硫含量低于500ppm、或低于50ppm，甚至低于10ppm的内燃机燃料，如柴油、煤油或汽油。
背景技术
众所周知，烃类混合物作为驱动交通工具的能源，一定要具有润滑性能，以保护其所能接触到的泵、喷射系统和所有的运动零部件。为了减少轿车、货车或公共汽车的排放污染，尤其是在楼宇密集的城市地区的排放污染，许多国家的法规都限定了燃料油中硫含量的上限，要求硫含量一般低于0.05wt％，或低于50ppm，甚至于低于10ppm。因此，炼油行业在日益改进其脱硫工艺，燃料油日益成为无硫、无芳烃和无极性化合物的清洁、无污染的产品。然而，上述这些组分却赋予燃料油良好的润滑性能。随着燃料油润滑性能的降低，将随之产生许多负面效应，如增加烃类混合物在运输和贮存过程中的静电问题。这样，就有必要在烃类混合物中添加其它化合物来代替上述这些化合物，无论净化与否，均能赋予烃类混合物良好的润滑性能，而添加的这些组分对环境无污染，具有较强的润滑能力可防止发动机磨损，并能减轻柴油本身固有的静电性和腐蚀性。
早期技术提出了许多方法以改善添加剂的润滑性和/或腐蚀性或润滑性和/或抗静电性。但尚未有文献报道，在改善发动机烃类燃料润滑性的同时，能减轻其腐蚀性、增强其导电性，并在达到相同使用效果时，添加剂的用量持平甚至降低。
不论是汽油、煤油或柴油，为了改善这些燃料油的润滑性能，建议 可以使用几种类型的添加剂。在润滑剂领域中，已知的主要抗磨剂有不饱和脂肪酸酯、二聚脂肪酸、脂肪胺、脂肪酸和二乙醇胺酯和长链一元脂肪酸等，这些组分在美国专利US2,252,889、US4,185,594、US4,204,481、US4,208,190和US4,428,182中都有所描述。大部分添加剂都具有优良的润滑性能，但添加的浓度也是相当高的，从经济角度讲这是它的一大缺点。另外，在车用润滑油中不能使用高浓度的含二聚酸的添加剂，因为燃料与润滑油接触时，这些酸会发生化学反应，生成不溶于油的沉积物，但是这与通常使用的清洁添加剂相矛盾。
美国专利US4,609,376主张在含醇燃料油中添加抗磨剂，在其组合物中，这种抗磨剂选自一元或多元羧酸酯和多元羟基醇。
另一选择是在燃料油中添加植物油酯或植物油，以提高燃料油的润滑性或光滑性。这些包括来自油菜籽油、亚麻油和葵花籽油的酯或上述油本身(参见专利EP635,558和EP605,857)。这些酯的一个主要缺点是当它们在燃料油中的浓度低于0.5wt％时，具有低的润滑性能。
为了解决这些问题，申请人已经提出在硫含量小于500ppm的燃料油中引入组分，该组分通过混合植物中的一元脂肪酸和一元多环芳香酸来获得，优选来自于植物并以酸、酯或胺盐的形式存在的组分(参见EP915944、EP1310547和EP1340801)。
目前工业生产商通过选择加入烃类燃料油中的混合物，以改善燃料油润滑性和导电性或润滑性和抗腐蚀性，该混合物可以合理的速率引入烃类中，并且该混合物的效率等于或好于其之前使用的产品，但有时是以更高的浓度引入的。因此，为了改善硫含量低于500ppm的烃类燃料在生产、运输和使用中的润滑性和减少静电积聚的危险性，WO01/88064提出一种燃料油组分，其包括硫含量低于500ppm的液体燃料油、至少一种0.001～1ppm的一元胺或N-取代基多元胺和至少一种10～500ppm含有8～24个碳原子的脂肪酸或相应的酯，该酯是含有最多8个碳原子的醇或多元醇。
WO97/45507提出在烃类化合物中引入化合物以提高润滑性，该化合物类型来源于酯化烯基酸酐，比例在5～5000ppm范围内变化。申请人发 现，通过添加这些化合物使燃料油的抗腐蚀性能得到了极大的改善。
尽管已有了这些改进，本发明的目是同时改善具有低硫含量烃类混合物的润滑性、抗静电性和抗腐蚀性，而依然能在达到相同使用效果情况下限制它们的用量。不论在水中是否以乳状液形式存在，甚至以某种润滑剂形式存在，它更为特别的目的是改善低硫含量燃料油、汽油、柴油和煤油的特性。
发明内容
本发明的主要内容是一种烃类混合物中具有润滑、抗腐蚀、抗静电性能的组合物，其包括：
a)至少一种如下式(I)的化合物A，其：
其中R1和R2是氢或带有1～40个碳原子的直链或支链烷基，烷基可以含有至少一个双键，R1和R2可以形成一个具有5～6个碳原子的芳香环或脂肪环，该环可以被1～3个带有1～40个碳原子的直链或支链烷基取代，其中R1和R2不能同时是氢。
其中R3和R4可以相同也可以不同，选自OH基，但两者不能同时是OH基；或衍生自官能度为2～5(含)的具有1～20个碳原子的直链或支链一元或多元醇基团；
b)至少一种化合物B，这是一种具有16～24个碳原子的脂肪酸，可以是饱和的也可以是不饱和的；可以是所述脂肪酸与至少含有芳香和/或烯属的多环(polycycle)或环的羧酸和/或它们的酯、酰胺或相应的胺盐衍生物的混合物，其单独使用或混合使用。
尽管化合物A和化合物B之间存在内在影响，值得指出的是这些化合物的组合物可以出乎意料地改善含有这些组合物的烃类混合物的润滑 性，而且增强了它们的导电性，同时还能减轻与烃类混合物接触的金属零部件的腐蚀程度。而且，还需指出的是该添加组合物与所有用作于燃料油和/或润滑剂的烃类混合物一样，具有对地面交通工具或飞机的驱动能力。
为了使在烃类混合物中具有最佳的润滑、抗腐蚀和抗静电效果，根据本发明，该添加组合物中含有至少一种以重量计为40％～70％的化合物A，至少一种以重量计为60％～30％的化合物B。
如果添加组合物中含有以重量计至少0.1％的化合物C，那么效果将提高，该化合物C选自C5～C30的一元和/或多元羧酸酯。这样的酯加入到本发明的中可以改善添加剂混合物的粘度，使其更好地分散到烃类混合物中。
在本发明中的优选方案中，这种组合物含有至少一种以重量计为40％～70％的化合物A；至少一种以重量计为60％～30％的化合物B；至少一种以重量计为0.1％～20％的化合物C。如果组成中含有至少一种以重量计为30％～60％的化合物A；至少一种以重量计为60％～30％的化合物B；至少一种以重量计为5％～20％的化合物C，那么这种组合物的润滑性和抗静电性的效果将会更佳。
为了达到良好的使用效果，下面将通过定义R1、R2、R3和R4基团，详细地描述化合物A、B和C。
化合物A一方面与R1和R2有关，另一方面也与R3和R4有关。表现出这些特性中任一种的任意化合物都可以视为本发明中化合物A的部分。
在式(I)的化合物A中，R1和R2可以是相同的也可以是不同的。在第一种方案中，R1是一种具有1～22个碳原子的烯基，而R2是氢或者反之亦然。
在第二种方案中，R1和R2形成一种有5～6个碳原子的芳香环或脂肪环，该环可以被1～3个带有1～3个碳原子的烷基取代。

优选，OR5基是-O-CH2-CH2-OH或-O-CH2-CHOH-CH2-OH或-O-CH2-C(CH3)(CH2OH)-CH2-OH或-O-CH2-C(CH2OH)-(CH2OH)-CH2-OH。
当然，若使用化合物A的混合物，也不会超出本发明的范围。
与此同时，本发明中的化合物B优选于含有至少一种碳原子数为10～24的直链饱和或不饱和羧酸和/或它们的酯、酰胺或胺盐衍生物。在这些酸中，优选油酸、亚油酸、亚麻酸、棕榈、硬脂酸、异硬脂酸和月桂酸，也可选它们的酯、酰胺和胺盐衍生物，其单独使用或混合使用。
更确切地说，大多数化合物B都是含有油酸和亚油酸和/或它们的酯、酰胺和胺盐衍生物的混合物。优先选择化合物B含有来自于植物、油菜、蓖麻、向日葵、玉米、椰子、松树或亚麻的直链脂肪酸和/或它们的酯、酰胺或胺盐衍生物的混合物，这些产品通常是商业产品。
化合物B优选通过来自松树油馏出物的直链脂肪酸和/或它们的酯、酰胺或胺盐衍生物的混合物来组成，不管这些酯、酰胺或胺盐衍生物来源于何处。
在本发明的另一实施方案中，化合物B包括树脂酸，其中包括松香酸、二氢化松香酸、四氢化松香酸、脱氢松香酸、新松香酸、海松酸、左海松酸、珀勒斯廷酸(parastinic acid)和/或它们的酯、酰胺或胺 盐衍生物。

当A1在室温呈固态时，在反应前应将其置于60℃的烘箱里。混合物中A1的比例超过50％时，为使其分散均匀有必要将其在烘箱里放置几分钟。
因此，化合物A1在化合物B1中的最大用量被室温下混合物的形态限定的。事实上对于室温下是液态的二元混合物来说，化合物A1的最大用量在80％(糊状混合)～60％(可流动但粘稠)之间。
然而，表III中结果表明混合物A1/B1具有良好的润滑效果。
使用50/50-A1/B1混合物可以得到最佳的效果，是兼顾HFRR效果和均匀性的最好的折衷方案。
但是，为了改善混合物A1/B1的粘度，在这些组合物中引入化合物Ci。
在柴油GO1中测试了混合物Ai/Bi/Ci的润滑性，柴油中该混合物的浓度是200ppm。在潜在的化合物Ci中，C1是菜籽油甲基酯或EMC。涉及Ai/Bi/Ci混合物的测试结果列于表IV。

兼顾粘度(40℃下在70～120mm2/s之间)和润滑性(＜350μm)，最好的折衷方案是混合物M7和M11，M8的粘度效果不佳。
实施例III
本实施例旨在描述根据本发明其它化合物Ai单独使用或与化合物Bi 和化合物Ci混合使用时的润滑效果。在其它化合物Bi中，B2是按1∶1比例B1与甘油反应所得的一种酯；B3是按1∶1比例B1与二乙醇胺反应的产物，结果见表V。

实施例V
本实施例旨在描述混合物Ai/Bi在导电性和抗腐蚀方面的显著效果。
柴油GO1中加入200ppm的混合物Ai/Bi。根据ASTM D2624-2标准测量导电性，根据ASTM D655标准测量腐蚀性。

即使单独使用化合物A1，测试的产品也具有良好的导电性并无腐蚀现象，但对于润滑性却不能一概而论(参见实施例II中表III)。
另一方面，化合物Bi具有低的导电性却有高的润滑性。
为了达到本发明的目的，有必要确立Ai、Bi和Ci之间的最佳折衷方案，使该方案在改善润滑性、导电性的同时又不存在腐蚀问题，最佳折衷方案是化合物A1/B1/C1的比例为43/42/15，此时润滑性在300μm～350μm之间。
实施例VI
本发明旨在描述在硫含量低于3000ppm的煤油中，混合物Ai/Bi在润滑性、导电性和腐蚀等方面的显著效果，结果见表VIII。
