Reaction Kinetics of N, N-ethyl(hydroxyethyl)hydroxylamine With Nitrous Acid

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 E_a of the reaction is (50.0±2.5) kJ/mol. The reaction rate increases with rising temperature, the concentrations of EHEH and HClO₄.
