Effect of Pressure in the Gamma Radiolysis of Cyclohexane in the Vapor Phase

Abstract

721than about six or seven carbon atoms, the randomisation of hydrogen atoms over the whole chain is unimportant but the elimination of olefins proceeds by complicated reaction steps not yet known. We thus think that, in its present state, the validity of the quasi-equilibrium theory for the prediction of the fragmentation pattern of alkyl radical ions is doubtful.We would like to express our thanks to Mr. G. Philippossian for his many hints on synthesis and to the Swiss National Foundation for the Encouragement of Research for a grant.

Disproportionation‐to‐combination ratios for cyclohexyl‐h11 and ‐d11 radicals in the gas phase as determined by the radiolysis of water vapor–cyclohexane mixtures

“…The product analysis was performed by a total sampling technique which incorporated a sample injection loop, a column with Igepal as stationary phase, and a temperature programmer as described earlier [13,14]. Figure 1 shows the G value of hydrogen, cyclohexene, and bicyclohexyl formed in the radiolysis of H20-c-CgH12 and H20-c-CgD12 vapor mixtures as a function of the cyclohexane concentration.…”

Self‐ and cross‐disproportionation‐to‐combination rations for cyclopentyl and cyclohexyl radicals and their deuterated analogues

“…The radiolysis products were analyzed by a Pye Unicam gas chromatograph equipped with an Igepal column and a 18652A Hewlett Packard integrator. Further details of the analytical technique have been described elsewhere [16,17]. Figure 1 shows the yields of hydrogen, cyclopentene, and bicyclopentyl formed in the gas-phase radiolysis of D~O -C -C~H~~ and D~O -C -C~D~~ mixtures as a function of cyclopentane concentration.…”
