The Adsorption and Reaction of Decomposition Products of Zinc Di-Isopropyldithiophosphate on Steel

Rates of adsorption and desorption of di-isopropyldithiophosphoric acid and tetraisopropylthioperoxydiphosphate from hexadecane on to EN31 steel have been measured using exp 14 C radiolabeled compounds. Concentrations, temp. and stirring dependence have been examined. The adsorption is surface contr...

Description
Summary:Rates of adsorption and desorption of di-isopropyldithiophosphoric acid and tetraisopropylthioperoxydiphosphate from hexadecane on to EN31 steel have been measured using exp 14 C radiolabeled compounds. Concentrations, temp. and stirring dependence have been examined. The adsorption is surface controlled and the kinetics can be represented by a Langmuir model. Correlation of rate data with antiwear properties is examined. 10 ref.--AA
