Abstract The elimination kinetics of 17 2-substituted ethyl N, N-dimethylcarbamates in the gas phase were determined in the temperature range of 269.5–420.2 C and the pressure range of 24–186 Torr. The reactions in a static system and in the presence of a free radical inhibitor are homogeneous and unimolecular and follow a first-order rate law. The kinetics and thermodynamic parameters are described. The use of several structure-reactivity ...
