The reaction of 2,6-dinitroanisole with cyclohexylamine in methanol and benzene–methanol was studied at several amine concentrations. Although the reaction rate in methanol is higher than in benzene, addition of small amounts of methanol to the benzene solution diminishes the rate of reaction (which is of third order in amine), reaching a minimum value at nearly 30% methanol, after which the rate increases
在几种胺浓度下,研究了2,6-二硝基苯甲醚与环己胺在甲醇和苯甲醇中的反应。尽管在甲醇中的反应速率高于在苯中的反应速率,但是向苯溶液中添加少量甲醇会降低反应速率(在胺中为三阶),在接近30%的甲醇中达到最小值,然后甲醇含量几乎呈线性增加。这里描述的这些和其他结果可以通过先前提出的反应方案令人满意地解释,其中胺的二聚体正在运行。
