Reactivity
2,6-XYLIDINE reacts with strong oxidizing agents [Handling Chemicals Safely 1980 p. 964]. 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.
