    Abstract: Polymethylene polyamine sulfonamides of alkyl-substituted phenolic sulfonic acids wherein the alkyl-substituent has a molecular weight within the range of 400 to 3000 are novel compounds soluble in mineral hydrocarbon oils of the lubricating oil range and as solutes therein are ashless addition agents imparting to the solution a combination of anti-oxidant and detergency-dispersancy properties useful in the lubrication of internal combustion engines. Illustrative of such sulfonamides are mono- and disulfonamides of hexamethylene diamine, tetraethylene pentamine, 2,6-di(aminoethyl) pyridine and N,N''di(aminopropyl) piperazine with 4-alkylphenolic sulfonic acids such as 4-alkyl-1-hydroxyphenyl, 4,4''-dialkyl-1,1''-dihydroxy2,2''-biphenyl, 4-alkyl-1-alkoxyphenyl or 2-tri- and tetra-(4''alkyl-1-hydroxybenzyl)-substituted 4-alkyl-1-hydroxyphenyl sulfonic acid chlorides.

    Abstract: Derivatives of dimeric nuclear carbon-to-carbon coupled palkylphenol have higher activity as lubricating oil addition agents than the same derivative of present p-alkylphenol. For example, sulfonamide or methylene-imine (i.e., product of Mannich Reaction) derivatives of dimeric coupled p-alkylphenol sulfonylchloride or dimeric coupled alkylphenol are more active dispersants than the same sulfonamide or methyleneamine derivative of the parent alkylphenolsulfonyl chloride or palkylphenol. Such dimeric p-alkylphenols can be prepared by oxidative coupling in aqueous alkaline medium in presence of potassium ferricyanide.

    Abstract translation: 二聚核碳 - 碳偶联的对 - 烷基酚的衍生物与现有的对烷基酚相同的衍生物具有较高的作为润滑油添加剂的活性。 例如，二聚偶联的对烷基苯酚磺酰氯或二聚偶联的烷基酚的磺酰胺或亚甲基亚胺（即曼尼希反应的产物）比母体烷基苯酚磺酰氯或对烷基酚的相同磺酰胺或亚甲基胺衍生物更具活性的分散剂。 这种二聚对烷基酚可以通过在碱性水溶液中在铁氰化钾存在下进行氧化偶联来制备。
