The pyrolysis of 2-nitropropane has been studied under both homogeneous conditions (using a continuous-wawe CO2 laser and sensitized by sulphur hexafluoride) and heterogeneous conditions (pulsed pyrolysis) at temperatures in the range 820-1210 K.A comparison of both decompositions is aided by the determination of spatial temperature profiles and the effective temperature in the laserdriven reaction by using calculations of the temperature distribution, thermocouple techniques and elimination of ethyl acetate as a 'chemical thermometer'.The main process in the laser-driven decomposition is the clean decomposition into propene and nitrous acid occuring via C-N bond fission.In heterogeneous pyrolysis additional products such as 2-nitropropene, acetonitrile and acetone are formed.The high yield of 2-nitropropene at 820 K indicates a unique route to this compound.
