Incompatible materials
... CAN REACT WITH OXIDIZING MATERIALS.
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
DI-N-BUTYLAMINE 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.
