The thermal decomposition of the ethoxyl radical has been studied in the gas phase over the temperature range 149–176° by use of the pyrolysis of diethyl peroxide as the radical source. Arrhenius parameters of 1012·15 sec.–1 and 22·1 kcal mole–1 were measured for the reaction EtO → Me + CH2O. The radical has been shown to decompose by carbon–carbon bond fission about an order of magnitude more quickly than by carbon–hydrogen bond fission.
