EMEROX® Azelaic Acids for Lithium Complex Grease
Azelaic acid is widely used as a complexing agent for lithium complex grease. It provides high dropping points along with improved mechanical stability, water resistance and oil separation properties. EMEROX® azelaic acid also has a lower melting point than other commonly used complexing agents which results in faster cycle times and improved ease of use.
Diesters made with azelaic acid are used as base fluids for lubricating greases which exhibit excellent viscosity/temperature relationships. Greases incorporating azelate base stocks are used in military and commercial aircraft engines, for electrical and other power requirements, for aircraft and space vehicle instruments, and for other equipment and instrumentation requiring maximum lubrication performance over a broad temperature range.

Frequently Asked Questions
What does azelaic acid do in lithium complex grease?
Azelaic acid acts as a complexing agent in lithium complex grease. It raises the dropping point and improves mechanical stability, water resistance and oil separation. EMEROX® azelaic acid also has a lower melting point than other commonly used complexing agents, which shortens cycle times and makes grease production easier. Emery offers EMEROX® 1110 and EMEROX® 1144 for this use.
Is azelaic acid the same as an azelate ester?
No. Azelaic acid (nonanedioic acid) is a C9 dicarboxylic acid, while an azelate ester is made by reacting azelaic acid with an alcohol. In grease, EMEROX® azelaic acid serves as a complexing agent for lithium complex grease. Azelate diesters serve as base fluids for greases that need excellent viscosity-temperature performance, such as those used in aircraft and instruments.
