Refractive Index:INDEX OF REFRACTION: 1.470
Water Solubility:Solubility in water: reaction.;soluble in molten sodium. Insoluble in ammonia, benzene,carbon tetrachloride, carbon disulfide and all organic solvents.
Storage Conditions:Store at RT.
Flammability characteristics:Hydrogen is combustible when exposed to water or humid air
Explosive limit:MODERATE WITH (ETHYLENE + MOISTURE), AIR, CHLORINE, FLUORINE, DIMETHYL SULFOXIDE, SULFUR DIOXIDE, WATER.
Odor:odorless
Experimental Properties:PARTICLE SIZE RANGE 5-50 MICRONS; STARTS TO DECOMP WITH EVOLUTION OF HYDROGEN @ ABOUT 225 °C
Air and Water Reactions:Highly flammable. Ignites or explodes in contact with air of high humidity [Bretherick 1979 p. 107]. Reacts violently with water producing a caustic solution (NaOH) and hydrogen (H2). Heat of reaction may ignite the hydrogen.
Reactive Group:Metal Hydrides, Metal Alkyls, Metal Aryls, and Silanes
Reactivity Alerts:Highly Flammable
Reactivity Profile:SODIUM HYDRIDE is a powerful reducing agent. Attacks SiO2 in glass. Ignites on contact with gaseous F2, Cl2, Br2, and I2 (the last at temperatures exceeding 100°C), especially in the presence of moisture, to form HF, HCl, HBr, and HI [Mellor 2:483 1946-47]. Reacts with sulfur to give Na2S and H2S [Bretherick 1979 p. 107]. Can react explosively with dimethyl sulfoxide [Chem. Eng. News 44(24):7 1966]. Reacts vigorously with acetylene, even at -60°C [Mellor 2:483 1946-47]. Spontaneously flammable in fluorine. Reaction with dimethylformamide, when heated, runs away [Chem. Eng. News, 1982, 60(28), 5]. Initiates a polymerization reaction in ethyl-2,2,3-trifluoropropionate such that the ester decomposed violently [Bretherick 5th ed. 1995]. Presence in the reaction of diethyl succinate and ethyl trifluoroacetate, has twice caused explosions [Chem. Brit., 1983, 19, 645].
