acetic anhydride organic synthesis
An organic acid anhydride is synthesized by the heating of two carboxylic acids at a high temperature of nearly 800℃.
In this process, one water molecule is removed from the reaction.
It can be synthesized by the reaction of a carboxylic acid with P2O5.
How do you manufacture acetic anhydride?
The preparation of acetic anhydride on a technical scale is carried out by oxidation of acetaldehyde or by reaction of acetic acid with ketone.
It is also known to prepare acetic anhydride by the reaction of acetic acid methyl ester and carbon oxide while using nickel catalysts (German Pat.
What is the purpose of acetic anhydride in your synthesis?
Acetic anhydride is the preferred acid derivative to synthesize aspirin commercially because the acetic acid produced in this reaction can be used again, by converting it back into acetic anhydride.
How is acetic anhydride prepared?
Acetic anhydride is prepared in the laboratory by heating sodium acetate with: ethyl chloride. conc.
