No effective replacement molecule for ZnDTP has been reported, to date. In an effort to understand why current replacement candidates are not sufficiently effective, we scrutinized the thermal chemistry of triphenyl phosphorothionate (TPPT) in oil by means of infrared and nuclear magnetic resonance spectroscopies. TPPT appeared to be both more thermally stable than ZnDTP (and therefore not activated under most conditions), as well as being a much less effective oxidation inhibitor — the original application of ZnDTP (2.39).

The same authors studied the thermal films produced by triphenyl phosphorothionate (TPPT) at 423 K. Also, in this case, the formation of short-chain ironfll) polyphosphate with a low amount of iron snlfafe was suggested [22]. In the tribotracks, short-chain ironfll) polyphosphate, iron sulfides, and sulfates were defected. Increasing sliding time induced an increase in the amormt of iron snUate. After 6 h, comparable amounts of iron snlfafe and phosphates were observed. These findings were explained by the authors with a decomposition temperature for triphenyl phoshoro-thionate of around 423 K. Following the adsorption, the thermal oxidative process took place after the breakage of the P=S bond, the formation of iron phosphate and sulfate was proposed to occur.
