Catalysis by hydrogen halides in the gas phase. Part XXII. NN-dimethylformamide and hydrogen chloride
Abstract
A homogeneous, molecular, gas-phase decomposition of dimethylformamide into carbon monoxide and dimethylamine catalysed by hydrogen chloride in the temperature range 335–415°C is described. The kinetic form is of the first order in amide and in hydrogen chloride. The overall bimolecular decarbonylation reaction obeys the Arrhenius equation k2= 1011·58 exp (–24,000/RT) cm3 mol–1 s–1
