picoSpin 45: Hydrolysis of Acetic Anhydride with Heavy Water (D2O) PDF

The acid-catalyzed hydrolysis of acetic anhydride has been studied by Kilpatrick (I) and by Gold and I-Iilton (23). It is i~sually accepted that the first step

The Hydrolysis of Carboxylic Anhydrides. V.12 The Acid Hydrolysis

The acid hydrolysis of trimethylacetic anhydride follows an A-2 mechanism in both water and aqueous di- oxane and is slower than that of acetic anhydride.
