Anwendungen & Verwendung
Beschreibung
Magnesium perchlorate is a powerful oxidizing agent, with the formula Mg(ClO4)2. Magnesium perchlorate decomposes at 250°C. The heat of formation is 568.90 kJ/mol. If water is added to magnesium perchlorate, the reaction is highly exothermic and may cause damage to the eyes. Thus, this salt should be added to a sufficient amount of water in order to form a dilute solution.Mg(ClO4)2·6H2O is composed of white, deliquescent crystals which are soluble in water and alcohol but explosive when in contact with reducing materials. This compound is used as a drying agent for gases. This salt is highly exothermic when added to water and releases steamy HCl gas. It can be dried to form the anhydrate by heating to 250°C under vacuum. The hexahydrate losses two molecules of water at 244°C in air and further decomposes to the dihydrate at 336°C and the anhydrate at 438°C. The anhydrate has been used as a desiccant to dry gas streams or air samples. However, it is no longer used since perchlorates tend to form explosive compounds with a variety of organic materials as well as other substances.
Verwenden
Magnesium perchlorate is commonly utilized as a potent oxidizing agent. It is used as dehydrating agent in organic synthesis. It is practiced in many domains like pharma industry, pyrotechnics industry,in rechargeable batteries and it is a versatile tool in organic synthesis. It possesses photoelectronic and optical properties. Thus it can be used in photo electronic and optoelectronic devices. It is applied as a strong drying agent for gases.
Herstellung & Synthese
synthetische
Magnesium perchlorate can be prepared by reacting magnesium carbonate with a solution of perchloric acid: MgCO3+ HClO4→Mg(ClO4)2+ CO2 This salt can also be prepared by an electrochemical method in water whereby magnesium perchlorate is formed from magnesium chlorate in which a platinum anode and a rotating stainless steel cathode are employed.
