2,5-Dimethylaniline Chemical Properties,Uses,Production

Chemical Properties

clear yellow to red-brown liquid

Uses

The uses are the same as those of xylidines.

Uses

2,5-Dimethylaniline was used in the synthesis of nanocomposite of multi-walled carbon nanotubes embedded in poly(2,5-dimethylaniline). 2,5-Dimethylaniline was used to study the effect of metabolites formed from 2,5-xylidine by fungi on laccase activity.

Uses

2,5-Dimethylaniline is widely used as raw materials to produce imaging chemicals like organic dyes and pigments. It is also used in the production of antioxidants, pharmaceutical, agricultural, rubber chemicals and other target organic molecules. 2,5-Dimethylaniline was also used in the synthesis of nanocomposite of multi-walled carbon nanotubes embedded in poly(2,5-dimethylaniline). 2,5-Dimethylaniline was used to study the effect of metabolites formed from 2,5-xylidine by fungi on laccase activity. The Fourier transform infrared (FTIR) and Raman spectra of 2,5-dimethylaniline was studied5. It induced transcription of lccIV.

Definition

ChEBI: A primary arylamine that is aniline in which the hydrogens at the 2- and 5-positions are replaced by methyl groups. It is used in the manufacture of dyes and other chemicals.

General Description

Dark brown liquid.

Air & Water Reactions

2,5-Dimethylaniline may be sensitive to prolonged exposure to air. Insoluble in water.

Reactivity Profile

2,5-Dimethylaniline 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

2,5-Dimethylaniline is combustible.

Safety Profile

Suspected carcinogen. A poison. Moderately toxic by ingestion. Quesuonable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also other xylidme entries.

Purification Methods

Convert p-xylidine to a derivative (see below) which, after recrystallisation, is decomposed with alkali to give the free base. Dry over KOH and fractionally distil. The acetyl derivative has m 142o (from H2O or toluene), and the benzoyl derivative has m 140o (from EtOH). [Beilstein 12 H 1135, 12 IV 2567.]
