摘　　要：The effect of temperature on the functional groups transition of N-methyl-N-nitroso-p-toluenesulfonamide （Diazald） and thermal decomposition were investigated by Fourier Transform Infrared Spectroscopy （FT-IR） and Differential Scanning Calorimeter （DSC）. The results showed that the functional groups transition of Diazald was temperature dependent, and thermal decomposition of Diazald was accelerated above 47.7℃. The HPLC-ESI-MS method was used for Diazald analysis, which indicated the strong hydrogen bonding between Diazald and water and instability of the NO group.
