acetic anhydride is obtained by the reaction of acetic acid and
What produces acetic anhydride on heating with acetic acid?
Acetic anhydride was first synthesized in 1852 by the French chemist Charles Frédéric Gerhardt (1816-1856) by heating potassium acetate with benzoyl chloride.
How does acetic anhydride react?
ACETIC ANHYDRIDE reacts violently on contact with water, steam, methanol, ethanol, glycerol and boric acid.
Reaction with water is particularly dangerous in presence with mineral acids (e.g., nitric, perchloric, chromic, sulfuric acid) [Chem.What is obtained by hydrolysis of acetic anhydride?
The hydrolysis of acetic anhydride in the presence of water is an exothermic reaction that produces acetic acid.
The esterification of acetic anhydride by ethyl alcohol can be represented by the following balanced equation: (CH3CO)2O A+ C2H5OHB ⟶ CH3COOC2H5 + CH3COOH.
