The reaction occurs at the ester with the water or hydroxy group attacking the carbonyl and then the alcohol, or salicylic acid, can act as a leaving group. Carboxylic acid consists of a carbonyl group (CO) and a hydroxyl group (OH). This table lists the locations and intensities of absorptions produced by typical functional groups. %PDF-1.3 I received consultant and speaker fees Bayer. Aspirin can be prepared by reacting salicylic acid and acetic anhydride in the presence of an acid catalyst. we have an amine here. I've see a lot of very Hydrolysis of Aspirin | Synthesis, Reaction & Mechanism - Video So ROH would be an alcohol. An aldehyde has a hydrogen directly bonded to this carbonyl carbon, but if there's no hydrogen, we're talking about a ketone here, so R, C double bond O, R, is a ketone. Prof. Ge has been engaged in clinical and scientific research work of cardiovascular disease since 1987, and his research area covers the pathogenesis of coronary heart disease, early diagnosis and treatment plan optimization. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Your own medicine cabinet may contain a bottle of aspirin. If acetic anhydride is used instead of acetic acid, the reaction is much faster and has a higher yield since acetic anhydride is much more reactive than acetic acid.
