Reduction with metallic powders to acetic acid, Destruction with aqueous sodium hydroxide, iron can also be used; Oxidation with, Boils to form vapor; pyrolysis at high temperatures yielding chlorine, hydrochloric acid and carbon monoxide, Extremely flammable, burns to release carbon dioxide, nitrogen gas and lots of heat, Yields carbon oxides, water vapor at high temperatures, Toxic to organisms, dangerous to aquatic and soil life, Incineration (no peroxides); Adding excess ferrous sulfate, sodium bisulfite or metabisulfite to neutralize the peroxides, followed by incineration; If the bottle has peroxides on the cap, do not open it, instead safely detonate it in a remote or special area, Extremely flammable, burns to release carbon dioxide and water vapors, Neutralization with base, bacterial degradation, decarboxylation, taken to waste disposal centers, Decomposes, releases combustion gasses, HF, methylene fluoride, Displays moderate toxicity to most organisms, Incineration (no peroxides); Acid-catalyzed hydrolysis with sulfuric acid; If peroxides are present, addition of excess ferrous sulfate, sodium bisulfite or metabisulfite to neutralize the peroxides, followed by incineration; If the bottle has peroxides on the cap, do not open it, instead safely detonate it in a remote or special area, Incineration; can be released in open air, Addition in large amounts of water or crushed ice, followed by addition of aq.
