스트론튬 수산화물 C화학적 특성, 용도, 생산
개요
Strontium Hydroxide occurs as an anhydrate whose prismatic, colorless crystals are deliquescent. A monohydrate and octahydrate are also known.Strontium hydroxide is slightly soluble in water but, surprisingly, the octahydrate is much more soluble. It is the latter that is supplied commercially for most applications.When the octahydrate is heated, seven waters of hydration are lost to form the monohydrate and finally the oxide.화학적 성질
colourless deliquescent crystals물리적 성질
White deliquescent crystal; density 3.625 g/cm3; melts at 375°C in hydrogen atmosphere; converts to oxide at 710°C; slightly soluble in water at 0°C, 0.41 g/100 mL, soluble in boiling water at 100°C, 21.83 g/100 mL; soluble in acids and ammonium chloride solution.The octahydrate consists of colorless, tetragonal, deliquescent crystals; density 1.90 g/cm3; loses all its water molecules at 100°C; sparingly soluble in water at low temperatures, 0.90 g/100 mL at 0°C; soluble in boiling water, 47.7 g/100 mL at 100°C; aqueous solution highly alkaline; soluble in acids and in ammonium chloride solution; insoluble in acetone.
용도
Strontium hydroxide [Sr(OH)2] is used to extract sugar from sugar beet molasses. It is also used in the manufacture of soaps, adhesives, plastics, glass, and lubricants that can be used in very high or low temperature environments.제조 방법
Preparation Strontium hydroxide is prepared by treating strontium oxide with water: SrO + H2O → Sr(OH)2Alternatively, Sr(OH)2 is made by heating strontium carbonate or strontium sulfide with steam at temperatures around 500 to 600°C: SrCO3 + H2O → Sr(OH)2 + CO2 SrS + 2H2O → Sr(OH)2 + H2S.
Purification Methods
Crystallise the hydroxide from hot water (2.2mL/g) by cooling to 0o.스트론튬 수산화물 준비 용품 및 원자재
