p-Toluidine Chemical Properties,Usage,Production

Chemical Properties
white lustrous plates or leaflets with an amine odour
ChEBI: An aminotoluene in which the amino substituent is para to the methyl group.
General Description
Colorless solid. Melting point 44°C (111°F). Specific gravity 1.046. Vapor heavier than air. Produces toxic oxides of nitrogen during combustion. May be absorbed through the skin. Used in dyes, and in organic chemical manufacturing.
Air & Water Reactions
Very slightly soluble in water.
Reactivity Profile
p-Toluidine neutralizes acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Can react vigorously with oxidizing reagents. Emits very toxic fumes of oxides of nitrogen when heated to decomposition. Hypergolic reaction with red fuming nitric acid [Kit and Evered, 1960, p. 239, 242].
Health Hazard
Absorption of toxic quantities by any route causes cyanosis (blue discoloration of lips, nails, skin); nausea, vomiting, and coma may follow. Repeated inhalation of low concentrations may cause pallor, low-grade secondary anemia, fatigability, and loss of appetite. Contact with eyes causes irritation.
Fire Hazard
Special Hazards of Combustion Products: Toxic and flammable vapors may form in fire.
