John Chia MBBS (Spore), MRCP (UK), FAMS (Spore), Lina Badimon BSc, PharmD, PhD, FESC, FAHA. The nitrogen of an amine does not need to be bonded to 2 hydrogens. Carboxylic acid consists of a carbonyl group (CO) and a hydroxyl group (OH). But we do still see a hydrogen transfer from the acetic acid to the salicylic acid: Let's briefly review. Trustee, Board of Trustees, American College of Cardiology. Make certain that you can define, and use in context, the key term below. Next let's look at aspirin. We would like to hear from you and have a chat, and maybe feature you on our podcast. 3. When you add water to the soluble aspirin, eg, sodium acetylsalicylate, it dissociates to form sodium ions and acetylsalicylate ions: Salicylic acid can react with acetic (ethanoic) acid in an esterification reaction, but the reaction is very slow, taking days to reach equilibrium, and the yield is low: For this reason, the commercial preparation of aspirin relies on the faster reaction between salicylic acid and the more reactive acetic anhydride which produces a greater yield of aspirin. Acetylsalicylic acid. Aspirin: Structure, Molecular Weight & Functional Group What is this functional group? Ionic salts of aspirin, such as sodium acetylsalicylate, are more soluble in water since they form stronger ion-dipole interactions with water. These functional groups include carboxylic acid, ester, and an aromatic group. The reaction that is used for the synthesis is the one between an excess of acetic anhydride that is added to a measured mass of salicylic acid in the presence of a catalyst, sulfuric acid. 4.
