    摘要: A novel crankcase dispersant reaction product having fused therein an antioxidant moiety whereby the dispersant reaction product can function as an antioxidant while retaining at least two structural domains, one being a polar domain for association with sludge and a hydrocarbyl domain for oil solubility, so that the dispersant can function as a chemical agent to suspend sludge and prevent agglomeration of sludge precursors and soot so the latter can be readily removed from the system, such as by filtering, instead of being deleteriously deposited on internal engine components, as well as lubricant compositions incorporating such novel dispersant and, for instance, engines lubricated with such lubricant compositions.

    摘要: Antioxidants for industrial, automotive, and aviation lubricants and methods of making the same are provided. A process using alkylated diphenylamines; alkylated phenyl-α-naphthyl amines; and a metal catalyst to form oxidates is provided. The metal catalyst is a combination of a cation and an organic anion, for example, a metal acetylacetone. The reaction takes place in the presence of oxygen to form an antioxidant comprising oligomers of the alkylated diphenylamine and the alkylated phenyl-α-naphthyl amine, and a metal component of the catalyst.

    摘要: An alkali metal sulfonate mixture for metalworking applications, a method for making the sulfonate mixture, and compositions containing the sulfonate mixture. The mixture includes a reaction product of a first synthetic mono-hydrocarbyl substituted sulfonic acid having from about 20 to about 50 carbon atoms in the hydrocarbyl substituent, a second synthetic mono-hydrocarbyl substituted sulfonic acid having from about 10 to about 16 carbon atoms in the hydrocarbyl substituent, and an inorganic alkali metal base. The reaction product has a number average molecular weight ranging from about 400 to about 500 and a substantially bimodal molecular weight distribution.
