Pulsed 6-Menv electrons from a Lineac were used ten initiate free radical reactions in the cyclohexane --oxygen system, The primary radical formed, cyclohexyl, is identified through EPR analysis of the irradiated solid sample at - 100 deg C, In the liquid phase the cyclohexyl -peroxy radical is formed; its decay is observed spectroscopically over a period of 10 msec, and the second- order rate constants calculated. The principal reaction involving the disproportionation of two cyclohexyl --peroxy radicals requires zero (< kcal/ mole) activation energy. The reaction rate constant is approximateIy 10/sup -4/ that for the diffusion-controlled process. (auth)
