This is not a complete listing of all incompatible substances but may be used as a guideline.

Substances in the left hand column should be stored and handled so that they cannot accidentally contact corresponding substances in the right hand column under uncontrolled conditions.

Chemical Is Incompatible with:
Acetic acid Chromic acid, nitric acid alcohols, ethylene glycol, perchloric acid, peroxides, permanganates
Acetic anhydride Hydryoxl-containing compounds such as ethylene glycol, perchloric acid
Acetone Concentrated nitric and sulfuric acid mixtures
Acetylene Chlorine, bromine, fluorine, copper, silver
Alkali and alkaline earth metals such as sodium, potassium, lithium magnesium, calcium, powdered aluminum Water, carbon tetrachloride and other halogenated alkanes, carbon dioxide, halogens
Aluminum alkyls Water
Ammonia, anhydrous (laboratory gas) Mercury (i.e. in pressure gauges), chlorine, calcium hypochlorite, iodine, bromine, hydrogen fluoride
Ammonium nitrate Acids, powdered metals, flammable liquids, chlorates, nitrates, sulfur, fine-particulate organic or combustible materials
