Novel alkylated diphenylamine derivatives of triazole and lubricating compositions containing the same

Abstract

Novel compounds are described, being alkylated diphenylamine derivatives of triazole, wherein the alkyl group on at least one of the phenyl groups is C8 or higher, in an amount ranging from 0.001 to 5.0% by weight of the lubricating composition. In particular, the derivatives may be 1-[di-(4-octylphenyl)aminomethyl]triazole; 1-[di-(4-nonylphenyl)aminomethyl]triazole; 1-[(4-octylphenyl)(4-butylphenyl)aminomethyl]triazole; and 1-[(4-octylphenyl)(phenyl)aminomethyl]triazole. A lubricating composition comprising the novel derivatives is also disclosed.

What is claimed is: 
     
         1 . A novel compound being an alkylated diphenylamine derivative of triazole, wherein the alkyl group on at least one of the phenyl groups is C 8  or higher. 
     
     
         2 . The compound of  claim 1 , being 1-[di-(4-octylphenyl)aminomethyl]triazole. 
     
     
         3 . The compound of  claim 1 , being 1-[di-(4-nonylphenyl)aminomethyl]triazole. 
     
     
         4 . The compound of  claim 1 , being 1-[(4-octylphenyl)(4-butylphenyl)aminomethyl]triazole. 
     
     
         5 . The compound of  claim 1 , being 1-[(4-octylphenyl)(phenyl)aminomethyl]triazole. 
     
     
         6 . A lubricating composition, comprising an alkylated diphenylamine derivative of triazole, wherein the alkyl group on at least one of the phenyl groups is C 8  or higher, in an amount ranging from 0.001 to 5.0% by weight of the lubricating composition. 
     
     
         7 . The lubricating composition of  claim 6 , wherein the derivative is chosen from one or more of the group consisting of 1-[di-(4-octylphenyl)aminomethyl]triazole;
 1-[di-(4-nonylphenyl)aminomethyl]triazole;   1-[(4-octylphenyl)(4-butylphenyl)aminomethyl]triazole; and   1-[(4-octylphenyl) (phenyl) amino methyl]triazole.
