Additional information
Proprionic anhydride rapidly hydrolyses to proponic acid in contact with water. Therefore data for biodegradation is based upon studies with propionic acid. Propionic acid is readily biodegradable (according to OECD criteria).
Rate constants:
Degradation rate in water: 4.7*10-2[d-1]1
Degradation rate in soil: 2.31*10-2 [d-1]2
Degradation rate in sediment: 2.31*10-3 [d-1]3
Degradation rate in air: 0.060 [d-1]4
