The kinetics of the aminolysis of different nitrophenylacetates were investigated with n-butylamine in dioxane at 20°C. The reaction rate can be described up to high concentrations of amine (~1 mole dm−3) by the equation v=k2[ester][amine]+k3[ester][amine]2. The ratio is larger for p-nitrophenylacetates than for o-nitrophenylacetates, while for 2,4-dinitrophenylacetates a third order term is not observed
用正丁胺在20℃的二恶烷中研究了不同硝基苯乙酸酯的氨解动力学。可以通过等式v = k 2 [酯] [胺] + k 3 [酯] [胺] 2来描述反应速率,直至高达高浓度的胺(〜1摩尔dm -3)。对-硝基苯基乙酸酯的比率大于邻-硝基硝基乙酸酯的比率,而对于2,4-二硝基苯基乙酸酯,没有观察到三阶项。
