摘要
在以提溴母液为原料的氯化镁生产中,硫酸镁及氯化钠等杂质直接影响产品质量,经过试验利用DTB结晶器生产晶体氯化镁可以有效降低产品杂质含量,产品中六水氯化镁含纯99%以上,达到食品添加剂标准,提高了产品档次,增加了企业效益。
In the production of magnesium chloride using the mother liquor of obtaining bro- mine, the impurities which contained magnesium sulfate and sodium chloride and so on influenced the quality of product directly. The impurity content of crystal magnesium chloride can be effectively reduced with DTB crystallizer by the experiment. The content of MgCl2 · 6H2O in the product ex- ceed 99% , which reached the standard of food additive, enhanced the level of product and in- creased the performance of enterprises.
