摘要:
为低成本制备无水氯化镁,实验采用半固相法,分别向Mg(OH)2-H2O体系和Mg(OH)2-无水乙醇体系中通入无水氯化氢进行氯化反应制备氯化镁。研究了反应温度与溶剂质量对不同体系下Mg(OH)2氯化效率的影响。对产物进行了氯化效率的检测和形貌分析。结果表明:Mg(OH)2-H2O体系具有更好的氯化效率:水加入质量为60 g,反应温度为200 ℃时,氯化效率为90%。扫描电子显微镜照片表明样品表面形成了疏松的氯化镁晶须且晶须生长完整,提高了氯化效率,对无水氯化镁的工业化生产具备一定的参考价值。
Abstract:
To prepare anhydrous magnesium chloride at low cost, anhydrous hydrogen chloride was introduced into the Mg(OH)2-H2O system and the Mg(OH)2-anhydrous ethanol system by the semi-solid phase method for chlorination reaction to prepare magnesium chloride. The effects of reaction temperature and solvent content on the chlorination efficiency of Mg(OH)2 in different systems were investigated. The chlorination efficiency and morphology analysis of the product were carried out. The results show that Mg(OH)2-H2O system has better chlorination efficiency: the chlorination efficiency is 90% when the mass of water is 60 g and the reaction temperature is 200 ℃. Scanning electron microscope images show that loose magnesium chloride whiskers are formed on the surface of the sample and grow completely, which improves the chlorination efficiency and has a certain reference value for the industrial production of anhydrous magnesium chloride.
