A review of zinc dialkyldithiophosphates (ZDDPS): characterisation and role in the lubricating oil

Tribology International, 2001
This is a review of the additive, zinc dialkyldithiophosphate (ZDDP), which is found commonly in lubricating oil where it plays a role as both an antioxidant and an antiwear additive. This zinc complex is highly effective but its mechanisms of action have not been definitively reported.

Determination of zinc dialkyldithiophosphate additives in lubricating oil by photometric titration

The Analyst, 1984
A photometric titration, using p-dimethylaminophenylmercury(II) acetate with Michler's thioketone as indicator, is described for the determination of zinc dialkyldithiophosphates in lubricating oils. The method is simple, rapid, reproducible and accurate and samples do not require separation or other preliminary stages prior to their analysis.
