This work is to study the reaction kinetics of AHA and HNO2 under HNO3 system. The reaction kinetic rate equation was found to be -dc (HNO2) / dt = kc (HNO2) c0.25 (AHA) c (HNO3). Under the conditions of t = 10 ℃ and I = 0.5mol · kg-1, the reaction rate constant k = (0.4814 ± 0.0375) L1.25 · mol-1.25 · s-1. The effect of reaction temperature on the reaction rate was experimentally studied. The result shows that with the reverse
