| titleOfInvention | A kind of preparation method of anhydrous magnesium chloride |
| abstract | A kind of preparation method of anhydrous magnesium chloride, it is preliminary first under HCl gas shields that low hydrate is obtained by the dehydration of magnesium chloride hyperhydrate, residual water is removed by chemical reaction then high-purity anhydrous magnesium chloride is obtained.Preliminary hydro-extraction temperature is relatively low, it is ensured that magnesium chloride does not occur to greatly reduce energy consumption while hydrolysis；In chemical reaction dehydration, dehydrant is obtained by sulfur, chlorine reaction, and intermediate species is constantly recycled, and chemical reaction dehydration makes product anhydrous magnesium chloride thoroughly depart from water environment, the side reaction product SO of generation 2 , HCl be gas, fundamentally avoid the generation of hydrolysis.This raw materials technology wide material sources are cheap, and whole technological process is good in economic efficiency, there is provided method strong operability, be easily achieved industrialization. |
