The Gamma Ray-Induced Addition of Acetaldehyde to Cyclohexene and Normal Hexene
By the radioinduced telomerization of acetaldehydehexene mixtures, methyl cyclohexyl ketone (McHK) was produced when cyclohexene was used, while methyl hexyl ketone (MnHK) and methyl isohexyl ketone (MiHK) were produced when normal hexene was used. The G(MnHK) at room temperature was found to be 400 (dose rate = 9.7 x 10⁴ r/hr), which is larger by a factor of ten than the G(MiHK) and the G(McHK). Irrespective of the dose rate, a G(MnHK) > G(McHK)> G(MiHK) relation always exists. It was found that: the G(MnHK) value, as well as the G(MiHk) and the G(McHK) values, increases with the rise in temperature, they all show however, maxima at 70 approximates 80 deg C, because of the thermal decomposition of the acetyl radical; sharp maxima are shown in the curves of G(telomer) vs initial composition at 5 mole% of hexenes; the analytical data of the gaseous products establish that the radioinduced decomposition of aldehyde and hexene occurs in parallel with the telomerization; and upon the addition of benzene or cyclohexane to the system, the G(telomer)'s decrease slightly in both systems, suggesting that they act as diluents rather than as agents of the energy transfer.
