Preparation of Anhydrous Magnesium Chloride from Magnesium Chloride Hexahydrate
TLDR
In this paper, a method for the preparation of high-purity anhydrous magnesium chloride by using magnesium chloride hexahydrate and ammonium chloride as raw materials, and alumina as covering agent was proposed.Abstract:
A method was proposed for the preparation of high-purity anhydrous magnesium chloride by using magnesium chloride hexahydrate and ammonium chloride as raw materials, and alumina as covering agent. X-ray diffraction was employed to investigate the process. The mechanism involved in the process was proposed. The factors affecting the purity of anhydrous magnesium chloride were investigated. Dehydrated ammonium carnallite was formed in the process to facilitate the dehydration process. Alumina as covering agent can guarantee that the formation of high-purity anhydrous magnesium chloride was obtained. The content of magnesia in anhydrous magnesium chloride was 0.02 pct under the optimum conditions: molar ratio of ammonium chloride to dehydrated magnesium chloride was 2:1, thickness of alumina 1.3 cm, reaction temperature 723 K (450 °C), reaction time 1 hour, and the number of crystallized water 0.6 to 2.2.read more
