Abstract：
 The present invention relates to chemical and metallurgical technology, and is especially process of preparing anhydrous magnesium chloride through dewatering bischofite. The process includes the first reaction of aniline hydrochloride and bischofite to produce aniline hydrochloride-magnesium chloride hexahydrate complex salt, the subsequent spray drying and pelletizing the complex salt, and final eliminating crystallized water and aniline hydrochloride in a fluidized bed to obtain the anhydrous magnesium chloride product. The present invention has the advantages of low power consumption, simple technological process, easy industrial amplification, environment friendship, stable product quality, etc.
