The Infrared Multiphoton Dissociation of Ethyl and Methyl Acetate
Abstract:
The collisionless decomposition of ethyl and methyl acetate was investigated using IR multiphoton dissociation. Ethyl acetate gave 97 percent concerted decomposition producing ethylene and acetic acid, the latter of which underwent significant secondary decomposition to ketene and water. Simple bond rupture producing ethyl radical and CH3CO2, which completely decomposed to CH3 and CO2, accounted for the remaining reaction products. Methyl acetate underwent concerted reaction to produce methanol and ketene, and simple bond rupture to form CH3 and CH3CO2, in near equal amounts.
