The effect of anionic surfactant, di-octylsodium sulphosuccinate (AOT) and nonionic surfactant, polyoxyethylene sorbitanmonooleate (Tween-80) on the hydrolysis of di-2,3-dichloroaniline phosphate was studied spectrophotometrically at 303 K. The influence of inorganic salts on the reaction rate was studied. The added salts viz. KCl, KNO3, and K2SO4 accelerated the rate of the reaction in the presence of anionic and nonionic micelles. The role of anionic and non-ionic micelle has been explained by the Menger-Portnoy, and Piszkiewicz models. The binding constant (Ks), rate constant (kψ) in the micellar phase, co-operativity index (n) and various thermodynamic activation parameters viz. ∆Ea, ∆S≠, ∆H≠, ∆G≠ etc. have been evaluated. Possible reaction mechanism has been proposed on the basis of the observed kinetic data.

胶束对水解di-2,3-dichloroaniline磷酸盐的影响

在303 K下分光光度法研究了阴离子表面活性剂磺基琥珀酸二辛基钠（AOT）和非离子表面活性剂聚氧乙烯脱水山梨醇单油酸酯（Tween-80）对磷酸2,3-二氯苯胺磷酸酯水解的影响。研究了反应速度。添加的盐即。在阴离子和非离子胶束的存在下，KCl，KNO3和K2SO4加快了反应速度。Menger-Portnoy和Piszkiewicz模型已经解释了阴离子和非离子胶束的作用。胶束相的结合常数（Ks），速率常数（kψ），协同系数（n）和各种热力学活化参数。评估了∆Ea，∆S≠，∆H≠，∆G≠等。根据观察到的动力学数据，提出了可能的反应机理。
