解説Sr(OH)2(121.63)．硝酸ストロンチウムの水溶液に低温で水酸化カリウムを作用させると八水和物が得られる．八水和物は無色の正方晶系結晶．密度1.90 g cm－3．水100 g に対する溶解度は0.80 g(20 ℃)，21.8 g(100 ℃)．空気中で風解して一水和物になりやすい．八水和物を100 ℃ に熱すると無水物が得られる．無水物は無色の粉末．融点375 ℃．密度3.62 g cm－3．吸湿性で強熱すると分解して酸化ストロンチウムとなる．二酸化炭素を吸収して炭酸ストロンチウムとなる．砂糖の精製，潤滑油やせっけんの製造，合成樹脂の安定剤，触媒，コンクリートの凍結防止剤，寒剤，冷熱剤などに用いられる．[CAS 18480-07-4:Sr(OH)2][CAS 1311-10-0:Sr(OH)2･8H2O]森北出版「化学辞典（第2版）

用途ストロンチウム水酸化物はその強塩基性を利用した多くの産業分野で使用されています糖蜜の精製や繊維の製造プロセスにおいては不純物を除去するためにこの化合物が用いられますまた環境保護の観点から二酸化炭素の吸収剤としての利用も研究されています

説明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.

使用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.

調製方法 · 2 件

製造方法Preparation Strontium hydroxide is prepared by treating strontium oxide with water: SrO + H2O → Sr(OH)2 Alternatively, 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.

純化方法Crystallise the hydroxide from hot water (2.2mL/g) by cooling to 0o.
