芳环上脱硝基氯化连续工艺的研究

STUDY ON CONTINUOUS PROCESS OF DENITRO CHLORINATION OF NITROAROMATICS

研究了硝基芳烃脱硝基氯化反应的连续工艺。由2-氟-5-氯硝基苯、2，5-二氯硝基苯和邻硝基氯苯的连续脱硝基氯化反应分别制得2，4－二氯氟苯、1，2，4-三氯苯和邻二氯苯，收率达90％。讨论了硝基芳烃的结构、引发剂及其各类、反应温度和氯气流量等因素对连续工艺的影响。

Continuous denitrochlorination of nitroaromatics in the presence of a free radicalinitiator was studied. Three chloroaromatics were synthesized via continuous denitrochlo-rination of the corresponding nitroaromatics in 89% to 92% yields, respectively. Effects offactors on the process were discussed.
