Magnesium sulfate monohydrate is used as a chemical substance. The production method is a place that everyone is more concerned about. To produce chemical products that meet the quality requirements, you need to master the correct production method. Here are two production methods. They are hot-melt immersion method and recrystallization method. I hope they can help you.
1. Hot-melt immersion method: In this method, magnesium sulfate monohydrate must first pour the magnesium sulfate mother liquor into the immersion device. Here, please note that the concentration of the magnesium sulfate mother liquor is 30g / 100ml. In the liquid tank, the volume ratio of these two solutions is 2: 1, and it should be noted that the mixed salt solution must have less than 30% MgSO4 and less than 35% sodium chloride. The above two solutions should be left at a temperature of 45-50 ° C for 4 hours. After 4 hours, the clear solution from which NaCl is removed should be cooled and crystallized at about 5 ° C. After washing, filtering, and drying, magnesium sulfate monohydrate is obtained. ,;
2. Recrystallization method: In this method, a certain amount of industrial magnesium sulfate is first put into a dissolution tank, poured into water, and left for about two hours. The precipitated heavy metal sulfate is filtered and removed. After centrifugation, the above magnesium sulfate is put into a container and dried and dehydrated to obtain magnesium sulfate monohydrate.
The above are the two production methods of magnesium sulfate monohydrate introduced to you. The different methods require different operating skills. Everyone should pay attention to the reasonable use of production knowledge when producing. No matter which method is used to produce To obtain magnesium sulfate products, the integrity of the entire process must be guaranteed, so as to avoid improper operation and failure in preparation.
