Eyring Activation Energy Analysis Of Acetic Anhydride Hydrolysis In Acetonitrile Cosolvent Systems, Nathan Mitchell
Eyring Activation Energy Analysis Of Acetic Anhydride Hydrolysis In Acetonitrile Cosolvent Systems, Nathan Mitchell
Electronic Theses and Dissertations
Acetic anhydride hydrolysis in water is considered a standard reaction for investigating activation energy parameters using cosolvents. Hydrolysis in water/acetonitrile cosolvent is monitored by measuring pH vs. time at temperatures from 15.0 to 40.0 °C and mole fraction of water from 1 to 0.750. This work utilizes a temperature controlled water bath and a Vernier glass-body pH probe with Vernier Logger Pro 3.10.1 software for automated data collection. Data analysis is used to determine observed kinetic rate constants under the assumption that hydrolysis is a pseudo-first-order reaction. Eyring plots were used to compare activation energy parameters under iso-mole fraction conditions. …
