acetic anhydride substitute
What is an alternative to acetic anhydride?
Interestingly, a further improvement of the sustainability of the process was achieved by carrying out the reaction with a stoichiometric amount of isopropenyl acetate, which is a “greener” alternative to acetic anhydride, as the only by-product is acetone, which is easily removed from the reaction mixture through 9 mar. 2022
Can we use acetic acid instead of acetic anhydride?
We can use acetic acid to produce acetic anhydride.
The key difference between acetic acid and acetic anhydride is that acetic acid is a simple carboxylic acid, whereas acetic anhydride is the dehydration product of acetic acid.Citric acid is used for adjusting the pH values of the dye-baths of different textile fabrics as an alternative to acetic acid.
How can I make 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.
