| Hazard Information | Back Directory | [General Description]
Dark brown liquid. | [Reactivity Profile]
2,5-XYLIDINE(95-78-3) 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. | [Air & Water Reactions]
This chemical may be sensitive to prolonged exposure to air. Insoluble in water. | [Fire Hazard]
This chemical is combustible. | [Chemical Properties]
clear yellow to red-brown liquid | [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. | [Uses]
The uses are the same as those of xylidines. | [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. | [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.] |
