Compositions comprising an alternative to di-isotridecyl adipate

Abstract

The present invention concerns compositions, and more specifically lubricating compositions, comprising an alternative to di-iso tridecyl adipate (DITA). The present invention therefore discloses compositions comprising di-(2-hexyldecyl) succinate, advantageously from a renewable source, and the uses thereof as lubricating compositions, in particular as hydraulic oils or engine oils.

1 . A composition comprising:
 di-(2-hexyldecyl) succinate, and   an antioxidant for lubricants and/or an anti-wear agent for lubricants.   
     
     
         2 . A process for the preparation of the composition according to  claim 1 , comprising a step of mixing di-(2-hexyldecyl) succinate with the antioxidant and/or the anti-wear agent. 
     
     
         3 . A method of lubricating an engine comprising applying an engine oil comprising the composition according to  claim 1  to an engine. 
     
     
         4 . Engine oil comprising a composition according to  claim 1 . 
     
     
         5 . Hydraulic oil comprising a composition according to  claim 1 . 
     
     
         6 . Gear oil comprising a composition according to  claim 1 . 
     
     
         7 . Metalworking oil comprising a composition according to  claim 1 . 
     
     
         8 . A process for improving the lubricating power and/or the hydrolytic stability and/or the oxidation stability and/or the compatibility with elastomers and/or the solvent power of a composition, comprising introducing di-(2-hexyldecyl) succinate into the composition. 
     
     
         9 . (canceled) 
     
     
         10 . A composition consisting of di-(2-hexyldecyl) succinate and a base oil. 
     
     
         11 . (canceled) 
     
     
         12 . The composition according to  claim 1 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin. 
     
     
         13 . (canceled) 
     
     
         14 . (canceled) 
     
     
         15 . The engine oil according to  claim 4 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin. 
     
     
         16 . The hydraulic oil according to  claim 5 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin. 
     
     
         17 . The gear oil according to  claim 6 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin. 
     
     
         18 . The metalworking oil according to  claim 7 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin. 
     
     
         19 . The composition according to  claim 10 , wherein the di-(2-hexyldecyl) succinate comprises at least 90% carbon of renewable origin.
