摘要
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。
An acidic coupling reaction between p-(-sulphatocthyl-sulphonyl) aniline es-ter and 1-amino-8-hydroxyl-naphthy1-3,6-disulfuric acid was studied. The results obtainedshow that 1 ,it is a second order reaction,the reaction activation energy is 9.29kJ and thehalf-life is 0.541 min at pH=3.25.2,only one product of the reaction could be found at pH<3.25 between 5 and 15℃. The relationship among the rate constants,pH and temperaturewas given.
