Acetic anhydride is a carboxylic acid anhydride commonly used for the acetylation of amines and alcohols

Product Description: 

Acetic anhydride is a carboxylic acid anhydride commonly used for the acetylation of amines and alcohols. It undergoes exothermic reaction on addition of water to form acetic acid. The photodecomposition of acetic anhydride has been studied over the temperature range from 60-160°C. The impact of treating pine wood with acetic anhydride has been investigated to evaluate the toughness of pine wood.
