Appearance:Silane is a colorless, flammable and poisonous gas, with a strong repulsive odor. It is easily ignited in air, reacts with oxidizing agents, is very toxic by inhalation, and is a strong irritant to skin, eyes and mucous membranes. Silane is lighter than air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. It is used in the production of amorphous silicon.
Density:0.680 g/cm3 @ Temp: -185 °C
Melting Point:-185 °C
Boiling Point:-112 °C
Flash Point:NA (Gas)
Water Solubility:decomposed by H2O; insoluble alcohol, benzene [HAW93]
Storage Conditions:Fireproof.|Store in a cool, dry, well ventilated location. Separate from alkalies, oxidizing materials, halogens, and air. Outside or detached storage is preferred.
Vapor Pressure:greater than 1 atm (NIOSH, 2016)
Vapor Density:Relative vapor density (air = 1): 1.3|1.11
Odor:Repulsive odor
Experimental Properties:Gaseous or liquid cmpd of silicon and hydrogen ... analogous to alkanes or saturated hydrocarbons.|Specific gravity: 1.44 g/L (gas)|Decomp rapidly at 500 °C, slowly at 250 °C; undergoes reactions such as addition to the double bond of olefins, although limited by the competing decomp reaction, forming cmpd such as ethyl silane; similar cmpd form with more unsaturated carbon cmpd, yielding an endless variety of organosilanes|Silane ignites spontaneously in air.
Air and Water Reactions:Highly flammable. Pure state ignites in air, the first seven to eight of the series 6H2n+1 ignite spontaneously in air at room temperature or slightly elevated temperatures [Mellor 1:376 1946-47]. Slowly reacts with water to form silicon hydroxides and hydrogen gas.
Reactive Group:Nitrides, Phosphides, Carbides, and Silicides
Reactivity Alerts:Highly Flammable
Reactivity Profile:Slowly reacts with water to form silicon hydroxides and hydrogen gas [Hydrides of the Elements of Main Groups I - IV 1971 p.513]. Silane burns in contact with bromine, chlorine or covalent chlorides (carbonyl chloride, antimony pentachloride, tin(IV) chloride). Even traces of the free halogens may cause violent explosions, when handling silane, extreme caution should be taken, [Mellor, 1940, Vol. 6, 220]. Mixtures of silane and nitrogen oxides, nitrous oxide, detonate very easily, [Chem. Abs., 1990, 112, 121711].
Autoignition Temperature:Pyrophoric
Flammable Limits:Lower flammable limit: 1.4% by volume; Upper flammable limit: 96 (est)% by volume|Flammable Gas (may ignite SPONTANEOUSLY in air).
Physical Dangers:The gas is heavier than air.
