| titleOfInvention | Process for producing high purity anhydrous magnesium chloride from hydrous ammonium chloride |
| abstract | The present invention comprises the steps of preparing an aqueous ammonium chloride by concentration and crystallization in the magnesium chloride aqueous solution of magnesite dissolved in an aqueous hydrochloric acid solution, by adding and mixing ammonium chloride;n n n Primary heat treatment of the hydrous ammonium chloride under reduced pressure or vacuum conditions; Andn n n After the first heat treatment, performing a second heat treatment at a higher temperature than the first heat treatment;n n n It relates to a method for producing high purity anhydrous magnesium chloride comprising a.n n n The method for producing anhydrous magnesium chloride according to the present invention has the advantage that a simple process and high purity anhydrous magnesium chloride can be prepared compared to the conventional invention. More specifically, unlike the conventional invention in the process of primary heat treatment of the aqueous ammonium chloride, the first heat treatment under reduced pressure or vacuum conditions to prevent the generation of impurities such as MgO generated in the dehydration process to prevent high-purity magnesium chloride There is an advantage to manufacturing.n n n n Water-Proof Ammonium Chloride, High Purity Anhydrous Magnesium Chloride, Decompression Rotary Kiln |
