The pyrolysis of propionitrile has been studied at seven temperatures over the range 789-850 K and pressures between 10 and 100 Torr.Under these conditions the principal reaction products which are formed by essentially homogeneous processes are hydrogen, hydrogen cyanide, methane, ethane, ethene, acetonitrile and acrylonitrile.For short reaction times (<3percent conversion) the products are formed at rates which do not vary noticeably with reaction time.A free radical chain mechanism has been proposed which accounts for all the above products.The chain initiating step is the reaction a resonance energy of 5.4 +/- 1.4 kcal mol-1 for the cyanomethyl radical.
