Summary
-
1.
A spectrophotometric method has been used to investigate hydrolysis of the dichlorides of phthalic and terephthaiic acids in aqueous dioxane.
-
2.
In both cases, the reaction rate in aqueous dioxane mixtures is described by a second order equation (first order in each reagent) and increases with increase in polarity of the medium in accordance with Kirkwood's equation for the interaction between two dipole molecules.
-
3.
The relation between the reaction rate and the polarity of the medium has been used to calculate the dipole moments of the activated complex formed in the hydrolysis of acyl chlorides.
