To address the issues of low reaction efficiency and poor safety in the traditional batch process for the alternative nucleophilic substitution （VNS） amination of 3，4-dinitro-1H-pyrazole， this study employed continuous flow microreactor technology to investigate its VNS amination synthesis process and reaction kinetics. Key parameters such as temperature， feed flow rate， and residence time were systematically examined for their effects on the VNS amination reaction. The optimal reaction conditions were determined as a molar ratio of 4-amino-4H-1，2，4-triazole∶3，4-dinitro-1H-pyrazole = 3.6∶1， temperature of 60 ℃， flow rate of 50 mL·min^-1， and residence time of 105 s， achieving a maximum yield of 71% with reaction time significantly reduced from 30 min to 105 s. Kinetic studies showed that the VNS amination reaction followed a first-order kinetic model， with an activation energy of 15.50 kJ·mol^-1； the fitted kinetic model was well-constrained by experimental data across the temperature range of 30-60 ℃.
