摘要 采用分光光度法研究HNO2与N,N-乙基,羟乙基羟胺(EHEH)在高氯酸介质中的反应动力学,得到了反应动力学速率方程。研究结果表明:当温度为25℃、离子强度为1.0 mol/L时,反应速率常数k=3.43(mol/L)-0.93.min-1,反应活化能Ea=(50.0±2.5)kJ/mol;升高温度、提高EHEH和高氯酸浓度,反应速率加快。 The reaction between N,N-ethyl(hydroxyethyl) hydroxylamine (EHEH) and nitrous acid was spectrophotometrically investigated in the medium of HClO4 and the kinetic rate equation was obtained. The rate constant k is 3.43 (mol/L)^-0.93 ·min^-1 at 25℃, I=1.0 mol/L and activation energy Ea of the reaction is (50. 0±2.5) kJ/mol. The reaction rate increases with rising temperature, the concentrations of EHEH and HClO4.
