Incompatible Chemicals

The following is a quick reference of incompatibilities for many chemicals commonly encountered in the laboratory. It is not a comprehensive list of all possible combinations and chemicals. For details on any chemical, check the MSDS.

  • Acetic acid with chromic acid, ethylene glycol, hydroxyl compounds, nitric acid, perchloric acid, permanganates, peroxides
  • Acetone with concentrated sulfuric and nitric acid mixtures, hydrogen peroxide
  • Acetylene with copper (tubing), bromine, chlorine, fluorine, iodine, silver, mercury and their compounds
  • Alkali metals (e.g. powdered aluminum or magnesium, calcium, lithium, potassium, sodium) with carbon dioxide, carbon tetrachloride, chlorinated hydrocarbons, flammable liquids, oxidizers, salt sulfur, water
  • Ammonia (anhydrous) with mercury, halogens, calcium hypochlorite, hydrogen fluoride
  • Ammonium nitrate with acids, metal powders, flammable fluids, chlorates, nitrates, sulfur, and finely divided organics or combustibles materials
  • Aniline with nitric acid, hydrogen peroxide, inorganic acids, oxidizers
  • Bromine with ammonia, acetylene, benzene, butadiene, butane, petroleum gases, hydrogen, sodium carbide, turpentine, and finely divided metals
