Acetic Acid → Magnesium Acetate

Participants

Reaction Steps

As for the light magnesium oxide used for preparing said slurry of magnesium salt and said slurry of magnesium hydroxide in said step 1), the specific surface area is ≧100 m2/g, and the content of MgO≧95% (at weight); the monoprotonic acid used for preparing the slurry of magnesium salt is acetic acid and/or nitric acid; the dosage of acetic acid and/or nitric acid is determined according to the mole ratio for its sufficient reaction with MgO; the solid content of the slurry of magnesium salt and the slurry of magnesium hydroxide is 10%-14% (at weight). To prepare said slurry of magnesium salt, said light magnesium oxide is at first stirred with water evenly and then glacial acetic acid and/or nitric acid is added to magnesia for sufficient reaction, so as to produce magnesium acetate and/or magnesium nitrate; when said glacial acetic acid and/or nitric acid is reacting with magnesia, the stirring rate reaches 300-600 revolutions per minute. The ferric iron salt used in step 1) is preferably ferric nitrate.
