Progress of Research on Synthesis,Structure and Application of Dialkyldithiophosphate Complexes

Dialkyldithiophosphate complexes play a role in antioxidation,antiwear,extreme-pressure and anticorrosion properties,which are widly used for fuel and lubricating oil additives and polymer antioxidants.This paper reviews the synthesis,structure and application of dialkyldithiophosphate complexes,and the crystal structures of dialkyldithiophosphate ternary complex containing nitrogen base ligands are discussed especially.
