How to remove the crystalline water in the crystalline hydration?IntersectionIntersection

The dehydration temperature is 116.7 ℃.In fact, it has been dehydrated since 80 ° C.After dehydration, the four -water and two -water compounds were generated, and then the temperature was rising to the water without magnesium chloride.It can even go to the hydroxide later, because the generated HCL is easy to volatilize and lose, causing the reaction to the form of hydroxide.
Originally, magnesium chloride in six aquatic water was better than the stability of water -free magnesium chloride.Although both are easy to solve.But the latter is easier to solve.
From Liushui to Waterless, it is now a problem that is more difficult to large -scale high -efficiency and high purity in the industry.You can refer to the relevant literature.

Do a DSC first, then determine the dehydration, decomposition temperature, and then determine the heating temperature

High temperature heating can cause its hydrolysis. The landlord can try to grind it into powder first, add water -free ethanol and mix it, and then dry it with vacuum filter.
