THE RADIOLYSIS OF ETHANOL. II. BINARY VAPOR MIXTURES
Benzene and cyclohexene cause a marked decrease in the hydrogen yield from the vapor phase radiolysis of ethanol. The experimental data were tested against the two reaction mechanisms that gave straight-line plots for the corresponding cyclohexane--protector systems. Bcth of these mechanisms also gave straight-line plots for the ethanol-protector systems. One mechanism involved scavenging of hydrogen atoms. The values of the kinetic parameters derived from this mechanism are quite similar in the cyclohexane and ethanol systems. The second mechanism involved the transfer of energy (excitation or ionization) from ethanol to the protector. The values of the kinetic parameters derived from this mechanism showed some differences between the ethanol and cyclohexane systems. One possible reason for the lack of resolution between the two reaction mechanisms might be that they both occur to comparable extents. Two mechanisms appear to occur to comparable extents in the liquid cyclohexane system. (auth)
