Alkylphenol Detergents

Abstract

The disclosed technology relates to hydrocarbyl- (e.g. alkyl-) phenol detergents and their salts, where the hydrocarbyl group includes moieties equivalent to 5 to 10 carbon branched polyene compounds. Such compounds and their salts are useful as lubricant additives.

What is claimed is: 
     
         1 . An alkylphenol detergent composition comprising at least one phenol moiety having a hydrocarbyl group attached thereto, the hydrocarbyl group comprising at least one oligomer comprising monomers equivalent to 5 to 10 carbon atom branched olefins. 
     
     
         2 . The alkylphenol detergent composition of  claim 1 , where the monomers are equivalent to 5 to 10 carbon atom branched polyenes. 
     
     
         3 . The alkylphenol detergent composition of  claim 2 , where the monomers are equivalent to isoprene. 
     
     
         4 . The alkylphenol detergent composition of  claim 1 , where the oligomer is a terpene. 
     
     
         5 . (canceled) 
     
     
         6 . The detergent composition of  claim 1 , wherein the oligomer is equivalent to a partially or completely hydrogenated form of a terpene. 
     
     
         7 . (canceled) 
     
     
         8 . The detergent composition of  claim 1 , where the hydrocarbyl unit comprises 15 to 60 carbon atoms. 
     
     
         9 . The detergent composition of  claim 1 , where the detergent comprises an alkylphenol moiety of any of formula: 
       
         
           
           
               
               
           
         
       
     
     
         10 . The detergent composition of  claim 1 , wherein the detergent is a sulfur-bridged phenate detergent, a sulfur-free alkylene-bridged phenate detergent, a salicylate detergent, or mixtures thereof. 
     
     
         11 . The detergent composition of  claim 1 , where the detergent comprises one or more alkali metals, one or more alkaline earth metals, or mixtures thereof. 
     
     
         12 . The detergent composition of  claim 1 , where the detergent is overbased.

         14 . (canceled) 
     
     
         15 . (canceled) 
     
     
         16 . The detergent composition of  claim 1 , wherein the detergent is a neutral or overbased salt of alkylsalicylic acid. 
     
     
         17 . (canceled) 
     
     
         18 . A lubricating composition comprising (a) an oil of lubricating viscosity and (b) the alkylphenol detergent composition of  claim 1 . 
     
     
         19 . The lubricating composition of  claim 18 , wherein the alkylphenol detergent is present from about 0.01 to about 2 wt % of the lubricating composition. 
     
     
         20 . The lubricating composition of  claim 18 , wherein the composition is substantially free of an alkylphenol-containing detergent wherein the alkylphenol is derived from oligomers of propene. 
     
     
         21 . The lubricating composition of  claim 18 , further comprising a zinc dialkyldithiophosphate. 
     
     
         22 . The lubricating composition of  claim 18 , further comprising a dispersant.

         24 . (canceled) 
     
     
         25 . The lubricating composition of  claim 18 , further comprising a phosphorus-containing antiwear agent chosen from (i) a non-ionic phosphorus compound, which may be a hydrocarbyl phosphite; or (ii) an amine salt of a phosphorus compound. 
     
     
         26 . The lubricating composition of  claim 18 , further comprising a thiadiazole.
