Description and Uses
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.
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.
