Preparation of Novel B, N, S-containing Tri(hydroxymethyl)propane Esters and Its Friction-reducing Performance as Additives in Rapeseed Oil

摘要

Three novel B, N, S-containing tri(hydroxymethyl)propane (TMP) esters with different alkyl chains were synthesized and characterized. Thermal degradation tests were performed to analyze their thermal stability using a thermo-gravimetric analyzer. The friction-reducing performance of the synthesized compounds as additives in rapeseed oil (RO) was evaluated with a four-ball tester. The results show that the novel B, N, S-containing TMP esters have excellent thermal stability and possess good friction-reducing behavior when they are used as additives in rapeseed oil.
