Products Description
Propionic acid is a clear colourless liquid with irritating odour, miscible with water and soluble in most organic solvents such as ethanol and ether. Chemically, it is acidic, can be neutralised with alkali to produce propionate, slightly more acidic than acetic acid; can be esterified, under certain conditions and alcohol reaction to produce propionate; also has a certain degree of reducibility, can be oxidised by strong oxidants.
