Notes:
The rates of elimination of seven cycloalkyl acetates containing between 5 and 15 ring carbons have been determined in a static system over a temperature range 280-370°C and a pressure range 35-234 torr. The unimolecular reactions, carried out in the presence of the inhibitor cyclohexene, are homogeneous in seasoned vessels and follow a first-order rate law. The rate coefficients are exemplified by that found for cyclopentyl acetate: \documentclass{article}\pagestyle{empty}\begin{document}$$\log {\rm}k_1 ({\rm s}^{{\rm - 1}}) = (12.68 \pm 0.14) - (179.8 \pm 1.5){\rm \,kJ\,mol}^{{\rm - 1}} {\rm (2}{\rm .303}RT)^{- 1}$$\end{document} The sequence of relative rates is analogous to that found in most solution reactions of these compounds. The contribution of ring strain to energy barriers of these compounds is described.
