  Imidazolines substituted in the 2-position are obtained by condensing N : N1-ethyleneurea, or an N : N1-ethyleneurea substituted at a carbon atom by a hydrocarbon radicle, with a monocarboxylic acid other than formic acid, the reaction occurring with elimination of water and carbon dioxide. In a typical example, N : N1-ethyleneurea and oleic acid, heated to 280-300 DEG C., yield 2-heptadecenyl-imidazoline. Examples are given also of the manufacture of imidazolines from N : N1-ethyleneurea and stearic acid, palmitic acid, benzoic acid, butyric acid, a - and b -naphthoic acids, diphenyl-4-carboxylic acid, carbazole-2-carboxylic acid, and an acid (molecular weight 238) obtained by the oxidation of paraffin. In a further example, N : N1-propylene urea is heated with benzoic acid to yield a mixture of 4- and 5-methyl-2-phenylimidazolines. Carbazole-2-carboxylic acid is obtainable by fusing 2-chloracetyl-N-acetylcarbazole with caustic potash.

  在2-位置取代的咪唑啉可通过将N：N1-乙烯脲或在碳原子上被烃基取代的N：N1-乙烯脲与除甲酸以外的一种单羧酸缩合而得到，反应发生时会排除水和二氧化碳。在一个典型的例子中，将N：N1-乙烯脲和油酸加热至280-300摄氏度，会生成2-十七碳烯基咪唑啉。还提供了从N：N1-乙烯脲和硬脂酸、棕榈酸、苯甲酸、丁酸、α-和β-萘甲酸、二苯基-4-羧酸、咔唑-2-羧酸以及通过对烷烃氧化得到的一种酸（分子量为238）制备咪唑啉的示例。另外，将N：N1-丙烯脲与苯甲酸加热可得到4-和5-甲基-2-苯基咪唑啉的混合物。咔唑-2-羧酸可通过将2-氯乙酰-N-乙酰咔唑与氢氧化钾熔融得到。

  This invention relates to oil soluble, nitrogen containing sulfonated polymers useful as additives for lubricating oil and fuel oil, which are effective as dispersants and viscosity modifiers. The polymeric dispersant additives are ionic polymers which comprise a back-bone substantially soluble in the fuel or lubricant, and pendant ionic groups which are sulfonic acid groups which may be neutralized with an ammonium cation or an amine. Polymeric dispersant additives of this type may be made which are particularly useful in crankcase lubricating oils for imparting viscosity improvement, varnish inhibition, oxidation inhibition and detergency to the lubricant. These additives may also impart rust preventive properties to the oil or fuel, and as V.I. improvers they can be formed to have particularly good low temperature viscosity effects in lubricating oil.

  本发明涉及可溶于油的含氮磺化聚合物，可用作润滑油和燃油的添加剂，这种添加剂可有效地用作分散剂和粘度调节剂。这种聚合物分散剂添加剂是离子聚合物，由基本上可溶于燃料或润滑油的骨架和可与铵阳离子或胺中和的磺酸基团组成。这种类型的聚合物分散剂添加剂特别适用于曲轴箱润滑油，可提高润滑油的粘度、抑制漆膜、抑制氧化和去污能力。这些添加剂还可赋予润滑油或燃料防锈特性，作为 V.I. 改良剂，它们在润滑油中可产生特别好的低温粘度效果。

  Hydrocarbon polymers such as ethylene copolymers may be reacted with unsaturated nitrogen-containing monomers or unsaturated carboxylic acids in the presence of a free radical catalyst such as a peroxide or azo free radical initiator and a chain stopping agent, e.g. a mercaptan to inhibit excessive cross-linking and branching. The copolymer grafted directly with the nitrogen-containing monomers may be utilized as an additive for oil and fuel compositions, particularly lubricating oil compositions as a V.I.-dispersant additive. The polymer reacted with carboxylic acid may be further reacted with amines, polyols, amino-alcohols, etc. to also form a V.L-dispersant additive.

  乙烯共聚物等烃类聚合物可与不饱和含氮单体或不饱和羧酸在过氧化物或偶氮自由基引发剂等自由基催化剂和硫醇等链阻断剂的存在下反应，以抑制过度交联和分支。 与含氮单体直接接枝的共聚物可用作油和燃料组合物的添加剂，特别是润滑油组合物的 V.I.分散添加剂。 与羧酸反应的聚合物可进一步与胺、多元醇、氨基醇等反应，以形成 V.L.分散添加剂。
