Abstract

Abstract As a multifunctional additive exhibiting antioxidant and antiwear activity for mineral lubricating oil, a composition of ammonium dialkyldithiophosphate (ADTP) with tetraalkyl thiuram disulfide (TDS) has been proposed, which provides lower sulfated ash, phosphorus, and sulfur contents compared with the traditional additive zinc dialkyldithiophosphate used for the same functions. Ammonium dialkyldithiophosphates bearing various alkyl radicals ...
