以对氨基苯乙烯砜硫酸酯（对位酯）与１－氨基－８－羟基－萘－３，６－二磺酸（Ｈ酸）为对象，研究了它们间的酸性偶合反应过程，并对之加以反应动力学的处理。结果表明：１）该反应在动力学上是一个二级反应。当ｐＨ＝３．２５时，反应活化能为９．２９ｋＪ。１５℃时，反应半衰期为０．５４１ｍｉｎ。２）当ｐＨ＜３．２５，温度在５～１５℃时，反应产物单一。给出了ｐＨ和温度影响酸性偶合反应速度常数的关系式。 The acidic coupling reaction between p-aminostyrene sulfone (p-ester) and 1-amino-8-hydroxy-naphthalene-3,6-disulfonic acid (H acid) To deal with the reaction kinetics. The results show that: 1) The reaction is a kinetic second-order reaction. When pH = 3.25, the reaction activation energy is 9.29kJ. At 15 ℃, the half-life of the reaction was 0.541min. 2) When the pH <3.25, the temperature at 5 ~ 15 ℃, the reaction product of a single. The relationship between pH and temperature affecting the rate constants of acidic coupling reaction is given.
