WebAlthough most of the reactions were carried out with acetic anhydride other acid anhydrides such as propionic and benzoic anhydride are also equally effective (entries 5, 6, 15, 16, 30 and 31). Acid chlorides can also be used for acylation under similar experimental conditions at room temperature (entries 7, 8, 17, 18, 32 and 33).

WebAppearance. Ethanoic anhydride is a colourless liquid, smelling strongly of vinegar (ethanoic acid). The smell is because ethanoic anhydride reacts with water vapour in the air (and moisture in your nose) to produce ethanoic acid again. This reaction with water is given in detail on another page.

WebAlthough this reaction can also be done with ethanoyl chloride, aspirin is manufactured by reacting 2-hydroxybenzoic acid with ethanoic anhydride at 90°C. The reasons for using ethanoic anhydride rather than ethanoyl chloride include: Ethanoic anhydride is cheaper than ethanoyl chloride. Ethanoic anhydride is safer to use than ethanoyl chloride. gmk silent key pcb mounted
