新型偶氮染料中间体2-氨基-3,5-二硝基苯乙酮的合成

Synthesis of a New Intermediate 1-(2-amino-3,5-dinitrophenyl)ethanone for Azo Dyes

本文以丙二酸二甲酯、镁屑、乙醇和2-氯-3,5-二硝基苯甲酸为原料,发展了一条新的路线合成新型偶氮染料中间体2-氨基-3,5-二硝基苯乙酮,该中间体可以生物降解,大大降低对人体以及环境的危害。

1-（2-amino-3,5-dinitrophenyl ）ethanone was synthesized from dimethyl malonate, magnesium shavings, ethanol and 2- chloro-3, 5-dinitrobenzoic acid. The intermediate could be biodegraded, which greatly reduced the harm to the human body and the environment.
