Stibine (H 3 Sb) as a colorless toxic gas with evil smell, resembling oxysulfide, -88 deg.] C melting point, boiling point -17 deg.] C, at -15 ℃ density is 4.344 times that of air, is generating Endothermic reaction, ΔH 298 Θ = 145.256 kJ ∕ mol. H 3 Sb is slightly soluble in water and is soluble in 5 L of water at room temperature. H 3 Sb is slightly soluble in alcohol and carbon disulfide. It can be slowly decomposed into helium and hydrogen at room temperature, and decomposes rapidly at 200 °C. Hydrogen halide has strong reducibility. When there is air or oxygen, it can be decomposed into helium and water at low temperature. When the temperature is increased, it can be burned to produce antimony trioxide and water.
