Abstract
Kinetics of a chemical reaction of cumylhydroperoxide with zinc diisooctyldithiophosphate (ZD) in dimethylformamide is studied by voltammetric techniques and a potentiometric method with a glass electrode. In the course of reaction, the activity of hydrogen ions first increases by two orders of magnitude and then decreases. The decomposition of cumylhydroperoxide during the second period is a second-order reaction, while the ZD transformation is a first-order reaction. In dimethyformamide, ZD is a weak electrolyte, and the current of its anodic oxidation is proportional to the square of the equilibrium concentration of diisooctyldithiophosphate ions.
