APPLICATIONS
Toluidine is the trivial name of methylaniline or aminotoluene. There are three structural isomers, ortho-TOLUIDINE, meta-TOLUIDINE, and para-TOLUIDINE. The names of the three compounds indicate amino group positions relative to the methyl group on the benzene ring. They can be obtained from coal tar as by-products in the fractional distillation or can be prepared by reducing nitrotoluene which are made by nitration of toluene. Toluidine is a compound homologous with aniline (the simplest aromatic amine) and similar properties aromatic amine. Toluidine is not soluble in water but in acidica queous solution. o-Toluidine and  m-Toluidine are clear to pale yellow, oily liquid. But p-Toluidine solidifies to an off-white crystalline solid at about 43 C as it has symmetrical structure . They are sensitive to air and light and tend to darken on storage. They are toxic if inhaled, ingested, or absorbed through the skin. Typical end-use markets for the toluidines and their derivatives are main materials for the synthesis of imaging products like pigment, dyestuffs,and photographic chemicals. All of these compounds are also used in the production of antioxidants, agricultural, pharmaceutical and rubber chemicals. N,N-Dimethyl-p-toluidine is used as a polymerization catalyst for Intermediate for polyesters and acrylate and epoxy resins. It can be used as a hardner for dental cements and in adhesives. It is used as an intermediate for photographic chemicals, colorants and pharmaceuticals.
