ChEBI: 2,4-dinitroaniline is a nitroaniline consisting of an aniline core having two nitro substituents located at the 2- and 4-positions.
생산 방법
2,4-Dinitrochlorobenzene is aminated with aqueous ammonia initially at 70 ℃; then the temperature is allowed to rise gradually to 120 ℃ to complete the reaction. Only a low-pressure autoclave is required, compared with the amination of 2- chloro- and 4- chloronitrobenzene.
일반 설명
Yellow powder or crystals with a musty odor. Sinks in water.
공기와 물의 반응
Insoluble in water.
반응 프로필
2,4-Dinitroaniline may decompose violently at elevated temperatures. 2,4-Dinitroaniline can react with oxidizing materials, i.e. chlorine/hydrochloric acid. . In mixture with powdered charcoal ignited upon heating, [Cahiers, 1980, (99), 278].
건강위험
May cause headache, nausea, stupor. Irritating to skin and mucous membrane.
Purification Methods
Crystallise the nitroaniline from boiling EtOH by adding one-third volume of H2O and cooling slowly. Dry it on a steam oven. The N-acetyl derivative has m 180o. [Beilstein 12 IV 1689.]
