二臭素酸マグネシウム

説明Magnesium bromate hexahydrate is a white crystalline compound that is insoluble in alcohol, but soluble in water. It reacts with methyl alcohol to form a complex. It is a fire hazard but is used as an analytical reagent.Magnesium bromate has found little usage in Industry because there are better oxidizing agents available. It is offered for sale commercially but in limited quantities.

使用Analytical reagent, oxidizing agent.

一般的な説明Crystalline solid. Soluble in water and denser than water. Hence sinks in water. Contact may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

製造方法Magnesium Bromate can be prepared by the reaction of bromic acid and magnesium carbonate: MgCO3＋ 2HBrO3→Mg(BrO3)2＋ CO2＋H2O However, magnesium bromate is not stable in an acidic environment and tends to decompose if one attempts to remove it from solution. Thus, the best method of preparation involves the use of sodium bromate which is basic enough to prevent such decomposition in solution: Mg(OH)2＋ 2NaBrO3→Mg(BrO3)2＋ 2NaOH The product is a hexahydrate, Mg(BrO3)2·6H2O This salt can also be prepared by adding a solution of magnesium sulfate to a suspension of barium bromate: MgSO4 (aq)＋ Ba(BrO3)2 (s)→Mg(BrO3)2 (aq)＋ BaSO4(s) The solution is then evaporated to recrystallize the hexahydrate, Mg(BrO3)2·6H2O.
