Magnesium chloride hexahydrate Usage And Synthesis

Description

Magnesium chloride hexahydrate is the hydrated form of magnesium chloride. Magnesium chloride is a mineral supplement used to prevent and treat low amounts of magnesium in the blood and a versatile compound with a number of uses in food preparation, health and personal well-being areas. Magnesium chloride is also used in road care, to synthesize other magnesium compounds, to remove dyes and industrial dye wastes, for the dust control, in the textile production, and as an industrial dye and dye waste remover. Magnesium chloride hexahydrate is used as catalyst for organic synthesis, e.g. 3,4‐Dihydropyrimidin‐2‐(1H)‐one. Magnesium chloride hexahydrate is also a promising heat/thermal storage material.

Chemical Properties

White crystalline powder

Uses

Used in adjustment of ion strength.

Definition

ChEBI: A hydrate that is the hexahydrate form of magnesium dichloride.

Purification Methods

Crystallise it from hot water (3.3g/mL) by cooling. Dry it in a vacuum at ~175o, or heat the hydrate in a stream of HCl. When the hydrate is heated above 180o it is hydrolysed to the oxychloride (Mg2OCl2). It is deliquescent; store it in a well-stoppered vessel.
