The kinetics of methane formation during the pyrolysis of ethane have been examined experimentally. It has been shown that under the conditions commonly used for the pyrolysis of hydrocarbons, the dissociation of ethane into methyl radicals is a first-order process of velocity constant log 10 k 1 = (17.45 ±0.82) - 91740 ±1400/2.303 RT (S -1 ) The kinetics of the free-radical chain decomposition of ethane are interpreted in the light of this and other experimental results.

Part I. Comparison of nitric oxide and propylene as inhibitors The reduction by propylene of the rate of pressure increase in the decomposition of propaldehyde at 550° has been shown by chemical analysis to represent a true inhibition of the reaction, and not to be due n an important degree to an induced polymerization of the propylene. With propaldehyde and with diethyl ether the limiting values to which the decomposition rates are reduced by nitric oxide and by propylene respectively are the same, although much more propylene is required to produce a given degree of inhibition. From this it is concluded that the limiting rates are more probably those of independent non-chain processes, than those characteristic of stationary states where the inhibitor starts and stops chains with equal efficiency.
