Erbumine (tert-butylamine) is a colorless liquid with an ammonia-like odor. It is used in the preparation of insecticides, pharmaceuticals, oil additives, and rubber accelerators. It 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 is generated in combination with strong reducing agents, such as hydrides.
