Uses for o-Toluidine
- Herbicides
- Rubber chemicals
- Dye and pigment intermediates
- Resin hardeners, fungicide intermediates and others
By far the largest use of o-toluidine is the preparation of methyl ethyl aniline (MEA, 6-ethyl-otoluidine), an intermediate in the manufacture of some herbicides, e.g. acetochlor, metolachlor, and propisochlor (Srour, 2002). Another important application of o-toluidine is the synthesis of rubber chemicals (Roempp, 1999), e.g. the rubber antioxidant di-tolyl-phenyl-p-phenylenediamine (DTPD) as well as the non-staining activator for rubber accelerators, di-o-tolyl-guanidine (DOTG) (Bowers, 2002). o-Toluidine is also converted into dye and pigment intermediates like acetoacet-otoluidine, 3-hydroxy-2-naphthoyl-o-toluidine, 2-toluidine-5-sulfonic acid, and o-aminoazotoluene. (Bowers, 2002). In addition, o-toluidine is used to manufacture epoxy resin hardeners such as methylene-bis-2-methylcyclohexylamine, fungicide intermediates such as 2-amino-4-methylbenzothiazole, o-fluorobenzoyl chloride.
