Abstract

The present invention relates to a lubricating composition comprising: from 0.1% to 30% by weight, with respect to the total weight of the composition, of at least one 2-octanol monoester of formula R1-C(═O)OR2, in which R1 denotes an alkyl group comprising from 8 to 36 carbon atoms and R2 denotes 1-methylheptyl, and at least one base oil. The invention also relates to the use of the 2-octanol monoester as additive in a lubricating composition.

Claims

exact text as granted — not AI-modified
1 .- 7 . (canceled) 
     
     
         8 . A lubricating composition comprising:
 0.1% to 30% by weight of the total weight of the composition, of at least one 2-octanol monoester having the formula R1-C(═O)OR2, wherein:
 R1 is an alkyl group of 8 to 36 carbons; 
 R2 is 1-methylheptyl; and 
   at least one base oil.   
     
     
         9 . The composition of claim  1 , wherein R1 is an alkyl group of 10 to 36 carbons. 
     
     
         10 . The composition of claim  1 , wherein R1 is an alkyl group of 10 to 26 carbons. 
     
     
         11 . The composition of claim  1 , wherein R1 is an alkyl group of 11 to 26 carbons. 
     
     
         12 . The composition of claim  1 , wherein R1 is an alkyl group of 12 to 24 carbons. 
     
     
         13 . The composition of claim  1 , wherein the 2-octanol monoester is 2-octanol palmitate. 
     
     
         14 . The composition of claim  5 , wherein the 2-octanol monoester is 2-octanol palmitate. 
     
     
         15 . The composition of claim  1 , wherein the base oil is selected from the group consisting of diesters, triesters, tetraesters, and mixtures thereof. 
     
     
         16 . The composition of claim  6 , wherein the base oil is selected from the group consisting of diesters, triesters, tetraesters, and mixtures thereof. 
     
     
         17 . The composition of claim  7 , wherein the base oil is selected from the group consisting of diesters, triesters, tetraesters, and mixtures thereof. 
     
     
         18 . The composition of claim  1 , further comprising an additive chosen from the group consisting of: antioxidants, metal passivators, corrosion inhibitors, viscosity index improvers, deposition inhibitors, detergents, dispersants, additives for protection against wear, and friction modifiers. 
     
     
         19 . The composition of claim  1 , wherein the composition is an emulsion.
