Abstract

The Pyrolysis of ethyl formate has been carried out in the temperature range 557°–630° and the rate expression k = 10^12.34^ e^−48,100±500/RT^ sec^−1^ was obtained, in agreement with the prediction of O'Neal and Benson [1]. Calculated Arrhenius A‐factors and experimental rate constants have been used to obtain the activation energies for the decomposition of the following compounds by the six‐center molecular mechanism (in kcal/mole): 2‐pentanone 59; methoxyacetone, 58; 2,4‐pentanedione, 51; methyl butyrate, ≥ 70; 1‐heptene, 54, and 4‐methyl‐1‐hexene, 54–55.
