| | Chemical of the Week -- Acetic Acid and Acetic Anhydride |
 | | Glacial acetic acid boils at 118°C, and has a density of 1.049 g/mL at 25°C. It is flammable with a flash point of 39°C. Through hydrogen-bonding interactions, acetic acid is miscible (mixable) in all proportions with water, ethyl alcohol, and diethyl ether. |
| | Acetic anhydride is a clear, colorless, mobile (free-flowing) liquid with a sharp odor similar to that of acetic acid. |
| | Acetic anhydride melts at —73°C, boils at 139°C, and has a density of 1.080 g/mL at 15°C. It is flammable with a flash point of 54°C. This compound is readily combustible and represents a fire hazard. |
