| Abstract: | Bischofite and ammonia were used as raw materials. Effects of concentration of magnesium chloride, concentration of ammonia and reaction temperature were studied. Through experiments, the optimum process conditions were obtained： the concentration of magnesium chloride was 2.5-3.1mol/L, the concentration of ammonia was 4.0mol/L, the reaction temperature was 50℃, and the reaction time was 60 min. |
