| 摘 要： | 在乙酸乙酯介质中，2，6-二氯-4-硝基苯胺（DCNA）经重氮化和还原脱氨基“一锅煮”方法合成出3，5-二氯硝基苯。乙酸乙酯不仅作两相反应的溶剂，而且也提供还原剂乙醇。反应过程中没有棕色的二氧化氮废气产生，酸耗量少．且无副产物如醚类生成。对反应中亚硝酸钠用量、硫酸浓度及用量、乙酸乙酯用量、反应温度等因素进行了研究。

| Abstract: | In ethyl acetate media 2,6-dichloro-4-nitroaniline reacted to give 3,5-dichloronitrobenzene through diazotization and reductive deamination in one-pot.Ethyl acetate displayed not only as a solvent for two-phase reaction,but also as a pro-reducing (agent).The process was satisfactory with little pollution of waste acid and waste gas and had no by-products(e.g.ether).The factors including amounts of sodium nitrite,sulfuric acid and ethyl acetate,and reaction temperature were investigated. |

| Keywords: | 3 5-dichloronitrobenzene ethyl acetate deamination two-phase reaction |
