Abstract
The radiolysis of cyclohexene in the presence of CO (1−10 × 10 5 Pa pressure) leads to the formation of: 2-cyclohexene-1-one; 2-cyclohexene-1-o1; bi-2-cyclohexene-1-y1; 3-cyclohexyl-cyclohexene; cyclohexanone; cyclohexanol; cyclohexane and bicyclohexyl; in addition to traces of formaldehyde; 2- and 3-cyclohexene-1-carboxaldehyde; cyclohexane-carboxaldehyde and dicyclohexylketone. The G i -value of each individual product was found to be a function of the CO concentration in the solution, e.g. G i (2-cyclohexane-1-one) = 1.05 at 1 × 10 5 Pa CO and 10.30 at 1 × 10 6 Pa CO, respectively (1 atm = 1.013 × 10 5 Pa). Experiments with deoxygenerated cyclohexane were also carried out, and the final products were analysed for comparative purposes. Probable reaction mechanisms are presented as an explanation of the results obtained.
