2,4-Dimethyl aniline Usage And Synthesis

Chemical Properties	colourless to yellow or dark brown liquid

Definition	ChEBI: A primary arylamine that is aniline in which the hydrogens at the 2- and 4-positions are replaced by methyl groups. A clear to yellow liquid, it is used in production of certain dyes, pesticides and other chemicals.

General Description	Dark brown liquid.

Air & Water Reactions	2,4-Dimethyl aniline may be sensitive to prolonged exposure to air. Slightly soluble in water.

Reactivity Profile	2,4-Dimethyl aniline ignites on contact with fuming nitric acid . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard	2,4-Dimethyl aniline is combustible.

Purification Methods	Convert uns-xylidine to a derivative (see below) which, after recrystallisation, is decomposed with alkali to give the free base. Dry it over KOH and fractionally distil. The acetyl derivative has m 130o, the benzoyl derivative has m 192o, and the picrate has m 209o. [Beilstein 12 H 1111, 12 IV 2545.]
