The reaction mechanism between nickel ion and butynediols in the electroless plating process was analyzed. The results show that the change of BOZ concentration is a quasi first-order reaction, the change of the nickel ion concentration is related to the BOZ density, and this change belongs to a higher order reaction. The reaction rate equation was determined as dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4. The activation energy of this process decreases as temperature increases, and it decreases with the BOZ concentration as 64-423 mg/L, it increases with the BOZ concentration as 123~240 mg/L. The S value is positively correlated to temperature, when the temperature is 80℃, the reaction rate and S value are the largest; while when the temperature is above 80℃ and BOZ concentration is over 160 mg/L, S value and the reaction rate decrease gradually.

结果表明，镀液中BOZ浓度的变化是准一级反应，镍离子的浓度变化与BOZ的浓度有关，属多级反应，其反应速率方程为dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4，反应体系的活化能E随温度的升高而减少，随BOZ浓度的变化而变化：当BOZ浓度在64~123mg/L时，E线性减少；在123~240mg/L时E线性增加。S随温度的升高而增加，当温度达到80℃时S值最大，反应速度最大；当温度超过80℃，BOZ浓度大于160mg/L时，蝎的值逐渐减少，反应速度降低。

The result showed that the oxidation reaction of abietic acid is first-order reaction during the initial period but then isn't first-order reaction because of oxidant film.
