Conductance of lactyl lactic acid in acetic acid-sulphuric acid mixtures (80% acetic acid and different concentration of sulphuric acid) has been measured at 45ºC. The equivalent conductance at infinite dilution and the association constants have been calculated using Fuoss and Kraus equation. Addition of sulphuric acid further lowers the rate and exhibits formation of ion-pairs, triple-ions and higher aggregates. Effect of ionic strength, Arrhenius parameters and other molecular concepts etc. have been studied to discuss the mechanistic implications.
