Potassium hydride Usage And Synthesis
Chemical Propertiesdispersion of tan powder in mineral oil
UsesOrganic condensations and alkylations.
HazardDangerous fire and explosion risk, evolves toxic and flammable gases on heating and on expo- sure to moisture.
Health HazardPotassium hydride react with the moisture on skin and other tissues to form highly corrosive sodium and potassium hydroxide. Contact of these hydrides with the skin, eyes, or mucous membranes causes severe burns; thermal burns may also occur due to ignition of the liberated hydrogen gas.
Fire HazardPotassium hydride is flammable solid that ignite on contact with moist air. Potassium hydride presents a more serious fire hazard than sodium hydride. The mineral oil dispersions do not ignite spontaneously on exposure to the atmosphere. Sodium hydride and potassium hydride fires must be extinguished with a class D dry chemical extinguisher or by the use of sand, ground limestone, dry clay or graphite, or "Met-L-X ? " type solids. Water or CO 2 extinguishers must never be used on sodium and potassium hydride fires.
Safety ProfileDangerous fire hazard by chemical reaction. Ignites spontaneously in air. Moderate explosion hazard when exposed to heat or by chemical reaction. Wdl react with water, steam, or acids to produce H2 which then igmtes. Can react vigorously with oxidizing materials. To fight fire, use CO2, dry chemical. Potentially explosive reactions with 0-2,4- dnitrophenylhydroxylamine, fluoroalkenes. Ignites on contact with air, oxygen + moisture, fluorine. Incompatible with Cl2, acetic acid, acrolein, acrylonitrile, (CaC + Cl2), ClO2, (H202 + Cl2), (CHFL + CH,OH), 1,2-dchloroethylene, maleic anhydride, (n-methyl-n-nitrosourea + CH2Cl2), nitroethane, NCb, nitromethane, nitroparaffins, o-nitrophenol, nitropropane, n-nitrosomethylurea, (nitrosomethylurea + CH2Cl2), H20, trichloroethylene, tetrahydrofuran, tetrachlorethane. When heated to decomposition it emits highly toxic fumes of K2O. See also POTASSIUM and HYDRIDES.
