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.
