对以氯仿为溶剂的对羟基苯甲醛溴化生成3-溴-4-羟基苯甲醛和3，5-二溴-4-羟基苯甲醛沉淀的反应提出通过物料衡算和求解溶解度方程组计算清液浓度的方法，并在此基础上建立了对羟基苯甲醛溴化反应的动力学方程式．该方程式的计算值与实验测定值的平均相对误差为6.37％．
The reaction of bromination of 3-bromo-4-hydroxybenzaldehyde and 3,5-dibromo-4-hydroxybenzaldehyde by bromination of p-hydroxybenzaldehyde with chloroform as solvent gave a new method to calculate the solubility of p- Liquid concentration method, and on this basis established the kinetic equation of p-hydroxybenzaldehyde bromination reaction. The average relative error between the calculated value of the equation and the experimentally measured value is 6.37%.
