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. 展开更多
