Some reactions of the isopropyl radical

The decomposition of ethane sensitized by isopropyl radicals was studied in the temperature range of 496–548°K. The rate of formation of n‐butane, isopentane, and 2,3‐dimethylbutane were measured. The expression k1/k2½ was found to be where k1 and k2 are rate constants of equation image The decomposition of propylene sensitized by isopropyl radicals was studied between 494 and 580°K by determination of the initial rates of formation of the main products. The ratio of k13/k21/2 was evaluated to be where k13 is the rate constant for equation image The isomerization of the isopropyl radical was investigated by studying the decomposition of azoisopropane. The decomposition of the iso‐C3H7 radical into C2H4 and CH3 was followed by measuring the rate of formation of C2H4. On the basis of the experimental data, obtained in the range of 538–666° K, k15/k2½ was found: where k15 is the rate constant of equation image
