| 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. |
| Application: | 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. It may also be used as a catalyst along with indium (III) triflate for the synthesis of tri/tetra-substituted imidazoles. |
| 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. |
