摘要
研究了(1)HNO_2与正丁醛的反应,得速率方程为:在20℃、I=2.0mol/kg时,速率常数k_1=0.761 ̄2/(mol ̄2·min);(2)在固定1.0mol/lHNO_3条件下,HNO_2与Np(Ⅵ)的反应,得速率方程为:在20℃、I=1.0mol/kg时,表观速率常数;(3)在固定1.0mol/lHNO_3条件下,HNO_2、n-C_3H_7CHO、Np(Ⅵ)共存时的反应,得速率方程为:在20℃、I=1.0mol/kg时,表观速率常数。结果说明,在HNO_2、n-C_3H_7CHO、Np(Ⅵ)并存时,首先发生反应的是HNO_2与Nn(Ⅵ)。
The kinetics of the reaction of nitrous acd with n-butylaldehyde and neptunium(Ⅵ)is studied and the results in different reaction systems are obained:(1)in system of nitrous acid withn-butylaldehyde,when t=20℃ and ion strengh I=2.0mol/kg,the rate constant k_1=0.761 ̄2/(mol ̄2·min );(2) in system of nitrous acid withNp(Ⅵ),when and I=1.0mol/kg,theapparent rate constant;(3)in system of nitrous acid and n-butylaldehydewith Np(Ⅵ),when and I=1.0mol/kg,the apparent rate constant .The results show that the nitrous acid has abigger reaction rate with Np(Ⅵ)than with n-butylaldehyde or n-butylaldehyde with Np(Ⅵ).
