Important Safeguards
vessel microwave digestion because they are highly reactive with oxidizing acids and/or may become nitrated and
potentially explosive. Absence of a particular chemical compound from this list does not imply microwave acid
decomposition of such a sample is safe under all conditions.
• Explosives (TNT, Nitrocellulose, etc.)
• Propellants (Hydrazine, Ammonium Perchlorate, etc.)
• Pyrophoric chemicals
• Hypergolic mixtures (Nitric Acid and Phenol, Nitric Acid and Triethylamine, Nitric Acid and Acetone, etc.)
• Animal Fats (Esters of glycerol capable of nitration and the formation of nitroglycerin or other nitrated organic
compounds)
• Aviation Fuels (JP-1, etc.)
• Acetylides
• Glycols (Ethylene Glycol, Propylene Glycol, etc.)
• Perchlorates (Ammonium, Potassium, etc.)
• Ethers (Cellosolve - Ethylene Glycol Phenyl Ether, etc.)
• Lacquers
• Alkanes (Butane, Hexane, etc.)
• Ketones (Acetone, Methyl Ethyl Ketone, etc.) and Alcohols (Methanol, etc.)
