参考来源 - 除草剂敌草快及其中间体的合成研究When the pH value was 7and 9, the mean activation energy(Ea)for hydrolysis of diquat was 21.33and25.89kJ·mol~(-1), respectively. The activation entropy(ΔS), which displayed striking relation, increased withthe increasing temperature, and the mean activation entropy was -191.83J·(mol·K)~(-1).
在pH为7和9的条件下,敌草快的水解活化能比较小,分别为21.33kJ·mol~(-1)和25.89kJ·mol~(-1),而敌草快水解反应的活化熵的绝对值变化随温度升高而增加,表现出显著相关性,其平均活化熵为-191.83J·(mol·K)~(-1)。
