examples

[0105]Lubricant Example 1 (EX1) is a 80W-90 gear oil lubricant containing 0.4 wt % of a Primene®81-R amine salt of oleyl phosphate and 0.15 wt % of 2-ethylhexyl tartrate.

[0106]Comparative Lubricant Example 1 (CLE1) is a gear oil lubricant similar to EX1, except it does not contain the tartrate.

[0107]Lubricant Example 2 (EX2) is a 80W-90 gear oil lubricant containing 0.4 wt % of a dibutyl phosphite and 0.15 wt % of 2-ethylhexyl tartrate.

[0108]Comparative Lubricant Example 2 (CLE2) is a gear oil lubricant similar to EX2, except it does not contain the tartrate.

[0109]Comparative Lubricant Example 3 (CLE3) is a gear oil lubricant similar to EX1, except it contains 0.15 wt % of 2-ethyl hexyl tartrate and 0.18 wt % of an amine salt of a thiophosphate as described by preparative examples 6 to 8 of International Patent application WO US09 / 036623 as described in paragraph [0107] of said application.

[0110]Comparative Lubricant Example 4 (CLE4) is a gear oil lubricant similar to EX1, except co...

Abstract

The present invention relates to an antiwear agent and lubricating compositions thereof. The invention further provides for a method of lubricating a driveline device application by employing a lubricating composition containing the antiwear agent.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation application of U.S. Ser. No. 13 / 390,790 filed on May 9, 2012, which claims priority to provisional application Ser. No. 61 / 234,722 filed on Aug. 18, 2009.FIELD OF INVENTION[0002]The present invention relates to an antiwear agent and lubricating compositions thereof. The invention further provides for a method of lubricating a driveline device by employing a lubricating composition described herein.BACKGROUND OF THE INVENTION[0003]One of the important parameters influencing durability or wear resistance of devices employing a lubricating composition is the effectiveness of phosphorus antiwear or extreme pressure additives at providing devices with appropriate protection under various conditions of load and speed. However, many of the phosphorus antiwear or extreme pressure additives contain sulphur. Due to increasing environmental concerns, the presence of sulphur in antiwear or extreme pressure additives ...
