DESCRIPTION
General description
Magnesium sulfate heptahydrate is hydrated salt of magnesium sulfate. It is hygroscopic in its anhydrous form. It can be used as a hydrophilic additive and as a catalyst in organic synthesis.
Application
Magnesium sulfate heptahydrate is used:
As an effective,catalyst for the condensation of o-phenylenediamine and 1,2-dicarbonyl compounds at room temperature.
As a catalyst in the synthesis of tri/tetra-substituted imidazoles from wide range of aromatic aldehydes, benzil, aliphatic and aromatic primary amines and ammonium acetate.
In the preparation of amorphous magnesium borates of various composition by interacting with sodium borate decahydrate.
Magnesium sulfate heptahydrate may be used as a catalyst for the condensation of o-phenylenediamines with 1,2-dicarbonyl compounds to form phenazine and quinoxaline derivatives.[1] It may also be used as a catalyst along with indium (III) triflate for the synthesis of tri/tetra-substituted imidazoles.[2]
