The thermal isomerization of acetonitrile to methyl isocyanide was investigated in the temperature range 1600-2100 K behind reflected shock waves. An Arrhenius expression for the low-pressure rate constant was obtained as, X-o/[Ar] = 10'3-40 esp(-159 kJ mol-'/f?7') cm3 moT' s-'. By connecting with t

Abstract
The isomerization of cycloheptatriene at high temperatures (800β1250Β°K) has been studied experimentally using a shock tube at high pressures and by very lowβpressure pyrolysis in the intermediateβpressure region (the first direct use of the latter technique for an isomerization). Rate coefficients obtained are in accord with previous results at lower temperatures. The results are examined theoretically to account for weakβcollision nonequilibrium effects. These corrections are found to be appreciable at the temperatures studied.
