Zinc dialkyldithiophosphates (often referred to as ZDDP) are a family of coordination compounds developed in the 1940s that feature zinc bound to the anion of a dialkyldithiophosphoric salt (e.g., ammonium diethyl dithiophosphate ). [1] These uncharged compounds are not salts.

Smith et al. [32] observed patches having Zn, Fe and S where P was not detected and discerned the existence of Zn, S and oxygen signals below phosphorous signal in XPS depth spectra [32].Thus they suggested presence of a dense iron/zinc sulphide/oxide on the steel substrate as a distinct layer under phosphate layer (see Fig. …

A wide variety of alcohols can be employed, which allows the lipophilicity of the final zinc product to be fine tuned. The resulting dithiophosphate is then neutralized by adding zinc oxide: P 2 S 5 + 4 ROH → 2 (RO) 2 PS 2 H + H 2 S 2 (RO) 2 PS 2 H + ZnO → Zn[(S 2 P(OR) 2] 2 + H 2 O Structural chemistry. In Zn[(S 2 P(OR) 2] 2, the zinc has ...
