What is the hydrolysis reaction of acetic anhydride?
- The hydrolysis of acetic anhydride is an exothermic reaction which is catalyzed under acidic conditions. The acetic anhydride hydrolysis reaction system is shown in Scheme 1. The hydrolysis reaction system of acetic anhydride is carried out under acidic conditions, and the hydrogen ions and hydroxyl ions ionized by water.
What is acidic hydrolysis?
- Acidic hydrolysis is simply the reverse of esterification. The ester is heated with a large excess of water containing a strong-acid catalyst. Like esterification, the reaction is reversible and does not go to completion. As a specific example, butyl acetate and water react to form acetic acid and 1-butanol.
What is hydrolysis of methyl acetate to acetic acid?
- In the hydrolysis of methyl acetate to acetic acid, the improvement comprising a flasher or stripper to separate methyl acetate and water from the hydrolyzer product stream and the recycle of these directly to the hydrolyzer.
How to separate ethanol and acetic acid in hydrolysis?
- You need to design a separation train that allows you to bring ethanol and acetic acid back to the main process while providing a recycle of ethyl acetate and water to the hydrolysis reactor.
