magnesium,ethoxyethane,dibromide - Introduction
Magnesium bromide diethyl etherate, also known as magnesium bromide diethyl etherate, chemical formula MgBr2(OC2H5)2, is an organic metal compound. The following is a description of the nature, use, preparation and safety information of Magnesium bromide diethyl etherate:
Nature:
Magnesium bromide diethyl etherate is a colorless or white crystalline solid, soluble in organic solvents such as ether and ethanol, insoluble in water. It usually exists in the form of anhydrous ether and has high stability.
Use:
Magnesium bromide diethyl etherate are commonly used as Lewis acid catalysts in organic synthesis reactions. It can be used for acylation, catalytic addition and condensation reactions of olefins, etc. In addition, it can also be used to synthesize other organomagnesium compounds, such as Grignard's reagent.
Preparation Method:
Magnesium bromide diethyl etherate are usually prepared by adding magnesium powder and bromide in anhydrous ether. Heating is required for the reaction to proceed, and the resulting product can be obtained by filtration or volatilization of the ether.
Safety Information:
Magnesium bromide diethyl etherate is relatively stable under normal conditions, but it is easy to hydrolyze to produce hydrobromic acid when exposed to humid environment or water. Hydrobromic acid is a strong acid, which is irritating and corrosive, so care should be taken to avoid contact with skin and eyes during use. In addition, Magnesium bromide diethyl etherate should also be stored in a dry environment to avoid contact with moisture and humidity.
