Zinc dialkyl dithiophosphate exported to Russia

Zinc dialkyldithiophosphate (ZDDP) is a widely used additive in lubricants, particularly in engine oils. Here’s an overview of zinc dialkyldithiophosphate and its role as a lubricant additive:

1. Chemical Structure: ZDDP is a complex chemical compound derived from the reaction of phosphorus pentasulfide, zinc oxide, and alcohol. It typically consists of a zinc ion bonded to two alkyl groups and two dialkyldithiophosphate groups.
2. Functionality:
   • Anti-Wear Agent: ZDDP forms a protective film on metal surfaces under high-pressure and high-temperature conditions, reducing friction and wear between moving parts.
   • Anti-Oxidant: It helps prevent oxidation and degradation of the oil by reacting with metal surfaces to form a protective barrier.
   • Corrosion Inhibitor: ZDDP provides corrosion protection for metal parts by forming a passivation layer that prevents metal-to-metal contact.
3. Applications:
   • Engine Oils: ZDDP is commonly used in motor oils for gasoline and diesel engines to protect engine components such as camshafts, bearings, and piston rings from wear and corrosion.
   • Industrial Lubricants: It is also used in gear oils, hydraulic fluids, and other industrial lubricants where high-load conditions are encountered.
4. Benefits:
   • Extended Engine Life: By reducing wear and protecting against corrosion, ZDDP helps extend the service life of engines and machinery.
   • Improved Performance: It contributes to smoother operation and enhanced reliability of mechanical systems by maintaining proper lubrication under varying conditions.
   • Compatibility: ZDDP is generally compatible with other additives commonly used in lubricants, but its effectiveness can be influenced by the presence of certain detergent-dispersant additives.
5. Regulations and Usage: Due to environmental concerns and the impact on catalytic converters in modern vehicles, the use of ZDDP in engine oils has been adjusted over the years. Lubricant formulations now often contain balanced levels of ZDDP to meet performance requirements while minimizing environmental impact.

In summary, zinc dialkyldithiophosphate (ZDDP) is a crucial additive in lubricants, providing essential anti-wear, anti-oxidation, and corrosion protection properties that help maintain the efficiency and longevity of engines and machiner
