Ester of thiolated butylated hydroxytoluene: Potential antioxidant for synthetic lubricant oil

Esters of thiolated Butylated hydroxytoluene (AO1 and AO2), bearing two antioxidant moieties (BHT and thioether), are synthesized and reported first time as competitive antioxidants for synthetic ester-based lubricant oil (trimethylolpropane trioleate, TMPTO). Differential Scanning Calorimetry (DSC)...
