Propanoic anhydride, also called Propionic anhydride, is a simple carboxylic anhydride. With the chemical formula (C2H5CO)2O, it is a widely used reagent in organic synthesis. Propanoic anhydride is strong smelling and corrosive, and will cause burns on contact with skin. Vapour can burn eyes and lungs.
Odor: Strong smelling, similar to vinegar
pH: 3 (100 g/l aq.sol.)
Vapor Pressure: 1.3mbar @ 20 deg C
Autoignition Temperature: 315 deg C
