Abstract
The thermal cis–trans isomerization of crotononitrile has been studied in the gas phase at pressures from 0.2 to 20 mm and temperatures from 300 °C to 560 °C. For the equilibrium cis → trans, ΔH = 0.17 ± 0.12 kcal/mole, and ΔS = −0.39 ± 0.19 cal/mole °K. The isomerization is a homogeneous, unimolecular, reversible first-order reaction, the rate constant for the reaction cis → trans being given by[Formula: see text]The only side reaction with appreciable rate was a surface polymerization.
