Appearance:Krypton, compressed, is a colorless, odorless gas. It is shipped as a liquid under its own vapor pressure. Contact with the liquid may cause frostbite to unprotected skin. It can asphyxiate by displacement of air. Exposure of the container to prolonged heat or fire may cause it to rupture violently and rocket.
Density:3.736
Melting Point:-157 °C
Boiling Point:-153 °C
Water Solubility:H2O: 59.4mL/1000g H2O (20°C) [KIR78]; Henry’s law constants, k×10?4: 3.685 (70.2°C), 4.017 (175.0°C), 3.761 (175.0°C), 2.392 (252.5°C) [POT78]
Vapor Density:Relative vapour density (air = 1): 2.9
Air and Water Reactions:No rapid reaction with air. No rapid reaction with water.
Reactive Group:Not Chemically Reactive
Reactivity Profile:These substances undergo no chemical reactions under any known circumstances. They are nonflammable, noncombustible and nontoxic. They can asphyxiate.|These substances undergo no chemical reactions under any known circumstances. They are nonflammable, noncombustible and nontoxic. They can asphyxiate. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].
Physical Dangers:The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.
