Carboxylic acids react with ammonium carbonate, to convert the carboxylic acids to ammonium salts. For example, acetic acid reacts with ammonium carbonate to produce ammonium acetate.[1]
After the reaction is completed, ammonium acetate is heated under reflux (170 °C) to dehydrate the salt and eliminate excess acetic acid and water producing acetamide [2]:
Usage
[edit]PET degradation
[edit]PET (Polyethylene terephthalate) belongs to the polyester family, it can be used for many purposes such as plastic bottles and filter cloth as it is thermoplastic polymer.[3] PET can be degraded by using aminolysis which works similarly to solvolytic reaction and aminoglycolysis. For aminolysis, PET reacts with DETA (diethylenetriamine) or TETA (triethylenetetramine) which is polyamine. The reaction involves 200 - 210 Celsius. From this reaction, the products are symmetrical primary amides, asymmetrical primary/ secondary diamides, and symmetrical secondary diamides. The remaining waste material products can be used for hardening of epoxy resins. Similarly, in solvolytic reaction, the polyester reacts with water, acid, amine or alcohol, and in aminoglycolysis reaction, the polyester reacts with TEA ( triethanolamine ). [4][5]
