✦ Synopsis

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:

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.

The gas-phase elimination kinetics of primary, secondary and tertiary b-hydroxynitriles were examined in static seasoned vessels over the temperature range 360-450 °C and pressure range 47-167 Torr (1 Torr = 133.3 Pa). These reactions are homogeneous, unimolecular and follow a first-order rate law.
