摘要
以２－氯－６－硝基甲苯为原料，经氯化得α，α，２，６－四氯甲苯，再经水解制得２，６－二氯苯甲醛。用ＧＣ／ＭＳ及ＧＣ／ＩＲ研究了氯化过程，发现反应温度是影响氯化过程的主要因素，通过正交实验，获得较优条件下２，６－二氯苯甲醛的总收率为６３７％。该法具有良好的工业化前景。
This paper deals with the synthesis of 2,6-dichlorobenzaldehyde by chlorinating 2-chloro-6-nitrotoluene to form α,α,2,6-tetrachlorotoluene and then hydrolysing the chloride.From GC/MS and GC/IR,It is shown that the reaction temperture is the main factor affecting chlorination.The total yield has reached 63 7%.The method is promising for industrial application.
