Magnesium bromide

마그네슘 브로마이드 C화학적 특성, 용도, 생산

화학적 성질

Colorless, very deliquescent crystals; bitter taste. Soluble in water; slightly soluble in alcohol.

용도

Organic syntheses, medicine (sedative).

용도

The major use of MgBr2 has been in the commercial production of bromine. The Dow process is an electrolytic method of bromine extraction from brine, and was Herbert Dow’s second revolutionary process for generating bromine commercially (1889).
Magnesium bromide has also been used in organic syntheses. An efficient and environmentally friendly procedure for the one-pot synthesis of tetrahydropyrimidines from aldehydes, a-diketones and urea/thiourea by using magnesium bromide as an inexpensive and easily available catalyst under solvent-free conditions has been described. Compared with the classical Biginelli reaction conditions, this new method has the advantage of good to excellent yields (74%–94%) and short reaction times (45–90 min). The structure of the Biginelli reaction product from a-diketone, salicylaldehyde and urea has been proposed to possess an oxygen bridge by cyclization (intramolecular Michael addition).

제조 방법

Magnesium bromide is prepared by treating MgO with hydrobromic acid and then crystallization above 0.0°C in solution. The product is the hexahydrate salt:
MgO+2HBr→MgBr2+H2O→MgBr2·6H2O
The anhydrous form may also be prepared by heating the hexah

Purification Methods

Crystallise it from EtOH or H2O (3.3g/mL). Dry it in a vacuum at ~150o, or heat the hydrate in a stream of HCl. It is very deliquescent. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 909 1963.]
