Health  
Flammability   1 Materials that require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur. Includes some finely divided suspended solids that do not require heating before ignition can occur. Flash point at or above 93.3 °C (200 °F). (e.g. mineral oil, ammonia)
Instability   3 Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked (e.g. ammonium nitrate, cesium, hydrogen peroxide)

2,4-Dinitroaniline Chemical Properties,Uses,Production

Chemical Properties

yellow crystalline solid

Definition

ChEBI: A nitroaniline consisting of an aniline core having two nitro substituents located at the 2- and 4-positions.

General Description

Yellow powder or crystals with a musty odor. Sinks in water.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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].

Health Hazard

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.]
