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.
