摘要 利用苦卤与工业氨水反应制备氢氧化镁滤饼,按比例将其与一定浓度的七水硫酸镁溶液置于高压反应釜中,通过水热反应制备碱式硫酸镁晶须,主要考察了物料配比、七水硫酸镁浓度、反应温度、搅拌速度和反应时间对晶须晶形的影响,得出适宜条件为:七水硫酸镁的浓度为08 mol/L,m(七水硫酸镁)∶m(氢氧化镁)为2∶1,反应温度为160 ℃,搅拌速度为300 r/min,反应时间为8 h。并对在此条件下合成的晶须进行了化学分析、电镜扫描(SEM)观察、X射线衍射(XRD)分析及TGDTG分析。

Abstract: The leached type Mg(OH)2 was prepared with brine and ammonia water as raw material. The leached type Mg(OH)2 and magnesium sulfate solution were put into the autoclave to prepare basic magnesium sulfate whiskers by hydrothermal reaction. The effects of concentration of magnesium sulfate heptahydrate, the temperature of the reaction, the rate of electric mixer, the raw material ratio, and the time of reaction on the preparation were discussed. The optimal experimental condition have been attained: The concentration of magnesium sulfate heptahydrate was 08 mol/L,the temperature of reaction was 160 ℃, the rate of electric mixer was 300 r/min, the raw material ratio of MgSO4.7H2O:Mg(OH)2 was 2:1, the time of reaction was 8 h. And SEM,XRD,TG-DTG were performed for analysis of basic magnesium sulfate whiskers.
