Anti-Wear Performance of Novel Tri(hydroxymethyl) Propane Esters as Additives in Rapeseed Oil

Article Preview

Abstract:

Three novel B, N, S-containing tri (hydroxymethyl) propane (TMP) esters were synthesized. The anti-wear performance of the synthesized compounds as additives in rapeseed oil (RO) was evaluated with a four-ball tester. The results show that the novel TMP esters have good antiwear performance when they are used as additives in rapeseed oil under all test loads. The action mechanism was investigated through analysis of the X-ray photoelectron energy spectrometer. The results indicate that the additives in RO adsorb and react with metal surface to form a protective film composed of organic compounds, B2O3 and iron oxide.
