摘要
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％．
For the bromization reaction of 4-hydroxybenzaldehyde in chloroform solvent,which results in precipitation of 3-bromo-4-hydroxy benzaldehyde and 3,5-dibromo-4-hydroxybenzaldehyde,the paper presents a method to calculate the concentration of clear liquid with material balance and solubility equations.Based on the above calculation a kinetics equation of 4-hydvoxybenzaldehyde bromization reaction is established.The average relative error between the values of experimental measurement and calculation is 6.37%.
