摘　　要：4,4-二硝基二苯乙烯-2,2′-二磺酸钠制备过程是对硝基甲苯邻磺酸氧化生成4,4′-二硝基二苯乙烷-2,2′-二磺酸钠;4,4′-二硝基二苯乙烷-2,2′-二磺酸钠再氧化生成4,4′-二硝基二苯乙烯-2,2′-二磺酸钠。通过对硝基甲苯邻磺酸次氯酸钠氧化合成4,4′-二硝基二苯乙烯-2,2′-二磺酸钠的反应实验,研究了对硝基甲苯邻磺酸次氯酸钠氧化反应过程机理,氧化过程是次氯酸钠参与游离基反应,主反应与次氯酸钠浓度无关。4,4′-Dinitrobibenzenyl-2,2′-disulfonic sodium was prepared as follow：first the p-nitrotoluene-o-sulfonic acid was oxidated to obtain,4,4′-dinitrobenzenyl-2,2′-disulfonic sodium,which then was oxidated to 4,4′-dinitrostibene-2,2′-disulfonic sodium.By the synthesis experiment of 4,4′-dinitrostibene-2,2′-disulfonic sodium by the sodium hypochlorite oxidation,the reaction mechanism was studied and it was proved that during the oxidation process,sodium hypochlorite takes part in the free radical reaction;the main reaction is independent of the concentration of sodium hypochlorite.
