    13 - Disposal Considerations

---

    SUBSTANCE DISPOSAL
    Under an inert atmosphere, cautiously add the material to dry
    butanol in an appropriate solvent. The chemical reaction may be
    vigorous and/or exothermic. Provisions must be made for the
    venting of large volumes of highly flammable hydrogen and/or
    hydrocarbon gases. Neutralize the solution with aqueous acid.
    Filter off any solid residues for disposal as hazardous waste.
    Burn the liquid portion in a chemical incinerator equipped with an
    afterburner and scrubber. Observe all federal, state, and local
    environmental regulations.
