For the first time, oleochemical sulfanes were synthesized via sequential vulcanization of fatty acid alkyl esters from rapeseed oil by benzoyl peroxide and elemental sulfur. Their structure and properties were established by the methods of instrumental analysis and it was shown that oleochemical sulfanes are complex structures with different cross-linking degrees, which provide excellent antioxidant and tribological characteristics and do not cause steel or copper corrosion under harsh test conditions.
