N,N'-Di-sec-butyl-p-phenylenediamine

dark red liquid

N,N''-di-sec-Butyl-p-phenylenediamine is used in method for preparing polyurethane adhesive.

Amber to red or dark reddish black liquid.

N,N'-Bis(1-methylpropyl)-1,4-phenylenediamine may be sensitive to prolonged exposure to air or light. Insoluble in water.

N,N'-Bis(1-methylpropyl)-1,4-phenylenediamine reacts with oxidizing materials. [NTP,1992]. 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.

N,N'-Bis(1-methylpropyl)-1,4-phenylenediamine is combustible.

Non flammable

Poison by ingestion. Moderately toxic by inhalation and sh contact. Corrosive to skin. A mild allergen. Symptoms of exposure are sweating, flushmg, shortness of breath, and slow pulse. Combustible when exposed to heat or flame; can react with oxidzing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.
