Kinetics of the hydrolysis of tetraethyl dithiopyrophosphate in aqueous dioxane solutions

1.The rate constants for the hydrolysis of tetraethyl dithiopyrophosphate in aqueous dioxane solutions of various compositions at 80°C and their temperature dependence in 50% dioxane solution have been determined.2.The constancy of the ratio of the hydrolysis rate constants of tetraethyl dithiopyrophosphate and tetraethyl monothiopyrophosphate with a change in the composition of the mixed solvents has been established, which indicates the mechanisms of the solvation of these compounds are similar.
