摘要：
Hydrated electrons (e(aq)-) formed in water radiolysis react with ethyl propionate with a rate parameter of 7.5x10(7) mol-1 dm3 s-1. The electron adduct in acidic solutions immediately (<100 ns) dissociates, yielding CH3CH2C=O radical. This process in alkaline solutions is slower, k=1.4x10(5) s-1. The hydroxyl radicals abstract H atoms in about 50% from the alpha-position of propionate.
