Kinetic Study of the Hydrolysis of Schiff Bases Derived from 2-Aminothiophenol

Journal of Solution Chemistry volume 41, pages 2036–2046 (2012)Cite this article

Abstract

The kinetics of the hydrolysis of Schiff bases derived from 2-aminothiophenol have been studied in aqueous sodium hydroxide media containing 40 % (v/v) methanol in the temperature range 22–45 °C. The Schiff base molecular structure-hydrolysis reactivity relationship has been investigated and discussed. Suitable reaction mechanisms have been suggested. From the effect of temperature on the rate constant, various activation parameters have been evaluated. The work has been extended to study the hydrolysis mechanism in buffer solutions of pH = 2–13 at 22 °C for Schiff base I (H). A rate profile diagram of pH-rate constant has been proposed.
