Baischem’s New Expanded Production Line for T591 metal deactivator Successfully Passes First Trial Run!

Recently, Baischem received significant good news —— the newly expanded production line for Petrocor® T591 (CAS: 91648-65-6) has successfully passed its first trial run! This marks a solid step forward in our capacity expansion and process optimization efforts.

 

About T591

 

T591 (CAS: 91648-65-6) is a high-performance ashless metal deactivator, appearing as a light yellow transparent liquid. It is a star product in the field of lubricating oils and metalworking fluid additives. Its core value lies in significantly improving oil performance at very low treat rates. With excellent anti-corrosion, anti-oxidation, extreme-pressure and anti-wear properties, as well as outstanding oil solubility and chemical stability, it is widely used in engine oils, industrial lubricants, gear oils, metalworking fluids, and the oil and gas industry.

 

T591 is a DMTD  derivative. DMTD itself can effectively inhibit corrosion of non-ferrous metals such as copper and impart excellent extreme-pressure, anti-wear, and antioxidant properties to oils, but its oil solubility is poor. Through modification of DMTD with tertiary nonyl mercaptan, Baischem has significantly improved oil solubility while fully retaining the core advantages mentioned above, making the product easier to formulate and more convenient to apply.

 

In practical applications, T591 demonstrates multi-faceted functional characteristics:

 

Corrosion Inhibition: Forms a dense protective film on metal surfaces, effectively blocking corrosive media such as oxygen and moisture to prevent rust and corrosion.

 

Metal Deactivation: Forms complexes with metal ions, retarding oxidation of oils and fuels. Provides significant protection for non-ferrous metals like copper.

 

Anti-wear Protection: Forms a robust lubricating film on metal surfaces, significantly reducing mechanical wear and extending component life.

 

Compatibility and Stability: Exhibits good compatibility with a wide range of base oils and can be flexibly combined with other additives, suitable for various automotive and industrial applications.

 

Conclusion:

 

The successful first trial run of this newly expanded production line not only further increases the production capacity of T591 but also demonstrates Baischem’s sustained investment in process innovation and quality control. The company is equipped with an advanced R&D center and has its own R&D, production, and quality control teams, providing full technical support from production to application. Our products break the foreign monopoly, fill the domestic gap, and achieve quality on par with international leading standards, delivering superior and stable products and services to our customers. If you are looking for a high-performance metal deactivator, Baischem is your reliable choice.
