Usage

Physical Properties

Anhydrous magnesium sulfate is a white crystalline solid occurring in alpha form as orthorhomic crystals or as a beta form having triclinic structure; density 1.507 and 1.502 g/cm3 for alphaand beta-forms, respectively; decomposes at 323°C; very soluble in water; moderately soluble in methanol (5.25g/100 mL at 15°C). The tetrahydrate constitutes colorless monoclinic crystals; hygroscopic; density 1.454 g/cm3; melts at 80°C; highly soluble in water (120 g/100mL at 15°C); very soluble in methanol and ethanol.

Uses

Different sources of media describe the Uses of 16674-78-5 differently. You can refer to the following data:
1. Magnesium acetate tetrahydrate is used in the manufacture of rayon fiber for cigarette filters; and as a fixative for dyes in textile printing. It also is used as an antiseptic and disinfectant.
2. Used in dialysis solutions.
3. Magnesium acetate [Mg(C2H3O2)2?4H2O] is used in the textile industry as a mordant (“fixes” dyes so that they will not run). It is also used as a deodorant and antiseptic.
4. Used as a source of magnesium in biological reactions, and as a source of acetate ion in chemical transformations. Acts as an emission control agent in coal combustion process to reduce acid rain. It is involved in glass formation process via the thermal decomposition of solids.

Chemical Properties

Colourless crystals or white or almost white, crystalline powder.
