The performance of lubricants and greases is critical in countless industrial and automotive applications, ensuring smooth operation, reduced wear, and extended equipment life. The formulation of these essential products often relies on specialized chemical additives, and azelaic acid (nonanedioic acid) has emerged as a valuable component in this sector. Its unique dicarboxylic acid structure lends itself to the creation of high-performance derivatives that enhance a wide range of properties in lubricant formulations.

Azelaic acid's primary contribution to the lubricant industry lies in its ability to form high-boiling diesters when reacted with monohydric alcohols. These diesters are known for their excellent performance characteristics, particularly in demanding applications. One key advantage of utilizing azelaic acid is its role in improving the low-temperature performance of lubricants. This means that lubricants formulated with azelaic acid derivatives can maintain their fluidity and lubricating capabilities even at significantly low temperatures, which is vital for machinery operating in cold environments.

Furthermore, azelaic acid lubricant applications extend to the formulation of greases, where it acts as an effective thickening agent. Greases formulated with azelaic acid-based thickeners often exhibit superior mechanical stability and enhanced water resistance compared to those using conventional thickeners. This improved stability ensures that the grease retains its structure and lubricating properties under stress and in the presence of moisture, prolonging its effectiveness and protecting the machinery.

The synthesis of azelaic acid itself, often through the ozonolysis of oleic acid, and its availability as a high-purity chemical intermediate (indicated by its azelaic acid CAS number 123-99-9) are crucial for its consistent application in the lubricant industry. The ability to produce these derivatives with high purity ensures that the final lubricant or grease products meet stringent performance specifications.

Moreover, the trend towards sustainable and bio-based chemicals also favors azelaic acid. Its derivation from renewable oleochemicals offers an alternative to purely petroleum-based lubricant components. This aspect is increasingly important for companies looking to reduce their environmental impact and meet growing consumer demand for eco-friendly products.

In summary, the integration of azelaic acid into lubricant and grease formulations provides tangible benefits: improved low-temperature performance, enhanced thermal stability, superior mechanical stability, and better water resistance. As the demand for high-performance, sustainable lubricants continues to rise, the role of azelaic acid as a key chemical intermediate is set to expand further.
