WebFeb 20, 2024 · From this point on, keep your flask under the hood, because it now contains acetic anhydride (the vapors of acetic anhydride are very irritating). Add about 5 drops of concentrated sulfuric acid. This will be the catalyst for the reaction. Place the flask in the boiling water bath and clamp it in place. (Fig.2) WebApr 7, 2024 · Boiling Point. Ethanoic anhydride's boiling point is at 140°C. This is only because it is fairly a big polar molecule, and so has both dipole-dipole attractions and van der Waals dispersion forces. However, it doesn't form hydrogen bonds. It means that the boiling point is not as high as that of a carboxylic acid of a similar size.
