Ammonium Acetate


Can Ammonium Acetate be made from Sodium Acetate and NH3 25%?

CH₃COONa + NH₄OH = NH₄CH₃CO₂ + NaOH

Should the NH3 25% be combined first with water? Thanks!

No Ammonia is a much weaker base than Sodium Hydroxide so the reverse reaction is favored. Also Ammonium Acetate tends to decompose when you attempt to evaporate it so you need to bubble Ammonia through glacial Acetic acid or react glacial Acetic acid with Urea

NH3 * HO2C2H3 + NaOH > NaO2C2H3 + NH3 + H2O

Ammonium Carbonate might work too.

These types of reactions favor products that are precipitates, liquids, or gases. Ammonium acetate and sodium hydroxide are both water soluble. However, ammonia could come off as a gas which would further give support that this reaction would support the other way around your equation ronstark.

If you think you have a good double displacement reaction in mind, check to see if at least one of your products is unaqeous.

Seems like bubbling NH3 in Acetic Acid is the way to go. We will see the yield at the end.

So, after some calculations, NH3 was bubbled inside an GAA solution. The solution became exothermic. How do you know when the reaction is complete? Ammonium Acetate is in liquid form. Upon cooling, the solution crystallizes out, indicating the presence of GAA and heating will form side products. Maybe let it evaporate @ RT?
