2-氯-4-硝基-2′-乙酰氨基-4′-(N,N-二烯丙基)氨基-5′-甲氧基偶氮苯的合成

Synthesis of 2-Chloro-4-nitro-2′-acetylamino-4′-(N,N-diallyl)amino-5′-methoxy azobenzene

以2-氯-4-硝基苯胺为起始原料,重氮化后与4-乙酰氨基-2-双烯丙基氨基苯甲醚偶合,经过滤、水洗得2-氯-4-硝基-2′-乙酰氨基-4′-(N,N-二烯丙基)氨基-5′-甲氧基偶氮苯。考察了原料配比、反应温度、反应体系pH值等因素对产品收率及纯度的影响。

Diazotized 2-chloro-4-nitrobenzenamine coupled with 4-acetylamino-2-(diallylamino)anisole,the product was filtered and washed with water,then,2-chloro-4-nitro-2′-acetamido-4′-(N,N-diallyl)amino-5′-methoxyazobenzene was prepared.The effects of factors such as molar ratio,reaction temperature,and pH of the reaction system on product yield and purity were investi-gated.
