APPLICATIONS

Xylidine is the trivial name of dimethylaniline, (CH3)2C6H3NH2. There are six structural isomers. The names of six compounds indicate methyl group positions relative to the amino on the benzene ring. They can be obtained from coal tar as by-products in the fractional distillation or can be prepared by heating aniline hydrochloride with methanol at 220 C. Xylidine is an aniline homologue and has similar properties of aromatic amine. Xylidines are brown liquids  at room temperature except 3,4-Xylidine. They are sparingly soluble in water but miscible with ethanol and diethyl ether. They are sensitive to air and light and tend to darken on storage. They are toxic if inhaled, ingested, or absorbed through the skin. Xylidines and derivatives are widely used as raw materials to produce imaging chemicals like pigments and dyestuffs. All of these compounds are also used in the production of antioxidants, agricultural, pharmaceutical, rubber chemicals and other target organic molecules.
