研究了3-氯-4-氟硝基苯液相氯化制2,4-二氯氟苯的影响因素。根据实验数据,建立了氯化反应精馏时的反应速率方程:r_0=k[3-Cl-4FNB][Cl_2]~(0.535)对于(?)20mm的填料塔,2,4-二氯氟苯的产率为9.1～14.5g/h。
The influencing factors of liquid chlorination of 3-chloro-4-fluoronitrobenzene to 2,4-dichlorofluorobenzene were studied. According to the experimental data, the reaction rate equation of chlorination reaction rectification was established: r_0 = k [3-Cl-4FNB] [Cl_2] ~ (0.535) The yield of benzene was 9.1-14.5 g / h.
