1.3 Synthetic Route
It is obtained by the reaction of magnesium carbonate with acetic acid. Add 80% acetic acid to water, heat to 60-80 °C, and add magnesium carbonate in small fractions until carbon dioxide no longer escapes. The solution is heated on a water bath and concentrated to a relative density of 1.25-1.26 when cooled. Filter out the crystals to obtain magnesium acetate tetrahydrate
