corresponding to two consecutive first-order reactions, with the rate constant of the second reaction considerably exceeding the rate constant of the first reaction, i.e., k 2 ie17-1} k 1. The temperature dependences of k 1 (s−1) in 47.59% HBr in the temperature range from 60 to 90°C and in 64.16% H2SO4 between 80 and 130°C are described by Arrhenius equations with IogA= 12.7 ± 1.5 and 13.6 ± 1.4 and
通过测压法研究了强酸(HBr,HCl,HClO 4和H 2 SO 4)浓溶液中甲氧基-NNO-氮氧基甲烷(I)水解的动力学。用对应于两个连续的一级反应的方程式描述气体逸出速率,其中第二反应的速率常数大大超过第一反应的速率常数,即k 2 ie17-1} k 1。在60至90°C的温度范围内,在47.59%的HBr中和在64.16%的H 2 SO 4中,k 1(s -1)的温度依赖性 用Arrhenius方程描述了80至130°C之间的温度,其中Iog A = 12.7±1.5和13.6±1.4,E a = 115±10和137±10 kJ / mol。在80-130 °C之间在64.16%H 2 SO 4中反应的速率常数k 2的Arrhenius方程参数为Iog A = 9.1±2.5和E a = 91±18 kJ / mol。对化合物I在浓H 2 SO 4中的UV光谱分析表明,I是弱碱\((pK_
