以苯酚为液化剂，探讨了不同催化剂对液化反应的影响，同时对其动力学特性及其树脂化进行研究，揭示了液化产物的性质随催化剂的变化规律。结果表明，当采用硫酸催化的液化产物其液化反应最快，而对于混合酸而言，因其酸性较弱，致使固化反应较慢，反应比较平稳。动力学研究表明，因为后期副反应缩聚反应的发生致使硫酸的活化能（87.41 kJ/mol）高于其他催化剂（76.48～83.78 kJ/mol）。同时，利用动力学特征值得出液化物反应速度以及反应活性顺序为：V（硫酸）：V 磷酸：V 对甲苯磺酸=1：00110120410101111。胶合性能实验结果表明，几种催化剂作用下的液化物树脂其强度均满足国标I类板的要求，当采用101作为催化体系时，其湿强度最高为1.24 MPa。

In this paper, using phenolic as the liquefying agent, the effect of different catalysts on the liquefying reaction and its kinetics as well as resinification reaction were studied and the varying patterns of liquefied products properties as the catalysts were revealed. The results showed that using H SO as the catalyst, the reaction rate was the2 4 quickest, and for the mixed acids, the curing rates were slower and the reaction was more smooth due to their weak acidity. The kinetics results showed that as the side reaction, polycondensation, in the late phase, the activation energy for sulfuric acid (87.41 kJ/mol) was much higher than that for the other catalysts (76.48-83.78 kJ/mol). Moreover, according to the kinetic parameter, the sequence of reaction rate and reactivity was obtained as follows: 1:0:0>1:1:0>1:2:0>4:1:0>1:0:1>1:1:1. And the results of bonding properties showed that the bonding strength of different liquefied resins met the requirements of grade I of standard GB/T9846-2004 and using the 1:0:1 as the catalyst, the bonding strength is the best, 1.24 MPa.
