WebThe SH stretching vibration in dialkyl dithiophosphoric acids [ (RO)2 PSSH] absorbs broadly in the liquid state at 2480–2440 cm −1. A band at 865–835 cm −1 is probably … WebThe SH stretching vibration in dialkyl dithiophosphoric acids [ (RO)2 PSSH] absorbs broadly in the liquid state at 2480–2440 cm −1. A band at 865–835 cm −1 is probably due to SH bending. Dithiophosphinic acids (R 2 PSSH) absorb broadly in the condensed state at 2420–2300 cm −1 due to SH S bonding. WebThis paper presents a critical review of state of the art in the qualitative and quantitative effectiveness of Zinc Dialkyl Dithio Phosphate (ZDDP) as anti-wear additive when in contact with wear debris under lubricated metallic sliding condition.
